Transforming Vintage Electronics from Worn to Working Since 2002

Welcome to the AMPTECH SYSTEMS web site and our TUBETVSHOP.COM portal.  We're a family-owned business.

Temporarily Downsizing to Part-Time

Due to current economic conditions & other factors beyond our control, we regret that we have been forced to temporarily downsize production to part-time capacity until further notice. Production capacity & turnaround times will be similar to those from 2003-2007 just after Jan passed away, but these setbacks are far less devastating than the loss of our co-founder had been & we hope that the length of the downsized period will be significantly less than 3 years, hopefully less than 1 year. We are still here and still active, but running with many team members taking time off for personal and/or medical reasons. We are also seeking temporary help & apprentices, but the recruiting, screening, & orientation process is taking quite some time due to the highly specialized skill sets required.

For 2015, we're making continuous upgrades to our offices, service shop, & web site. The fresh perspectives brought by new members of the Amptech Systems / TUBETVSHOP.COM team is expected to open a new chapter in the ongoing development of one of the nation's most recognized providers of professional Restoration service for Vintage TV & Electronics so that we expect to return to full-time production following the temporary setbacks much stronger than ever before.

ATTENTION: Due to several staff members dealing with significant personal health problems & requiring time to recuperate, there has been an extended Winter Break for the 2014 - 2015 season. We are currently adding new members to our Technical Team to fill in and to expand our capacity. We expect to complete significant upgrades as an ongoing process throughout 2015. For now, we will focus on completing backlogged work & training new staff members along with upgrading equipment. All new Restoration Request submissions will be advance reservations for Summer 2015.

Car accident injuries, surgery, & other issues affecting some staff members have resulted in several members of the team taking medical leave or being placed on light duty per doctors' orders. We are training newcomers to the team to fill in during these absences, & we expect everyone to be back & in great shape in a few months.

New for 2015

Our goal for 2015 is continued expansion of our Restoration capabilities.  Making high-quality Restoration services affordable for any "Family Heirloom" Radio, TV, or similar device has been an Amptech Systems tradition since 2002.  We're a lot like the old-fashioned "Mom & Pop's TV Shop" of some 50 years ago.  We're more than a web presence; we're people with names like John, Dave, Ann, and Todd.  Yes, we can even do in-home Service Calls for our semi-local clients after initial Restoration (northeastern Ohio / northwestern Pennsylvania ... ask about our Field Service availability area). We have also upgraded our office space with faster computers and network infrastructure.

More Upgrades for 2015

Beginning in April of 2015, I'll be designing a new workstation specifically for rebuilding of components for which no suitable replacements are available from any source. A few sets have been here too long awaiting replacements for special order parts we simply cannot find from any vendor. To service these and future tough cases similar to them, we'll be taking some extreme measures, basically adding a new service bench specifically for performing the electronic analog of microsurgery to actually rebuild these faulty parts to the best of our ability. We expect the new setup that we've named "MicroTech64" to be fully developed, installed, and ready for use in approximately June of 2015. More information will be posted here as the project develops.

Spotlight on Tube Audio for 2015!!!

Because tube audio was the original inspiration for the Amptech Systems name, professional servicing of Hi-Fi, Phonograph, Guitar Amplifier, and other Tube Audio has always been among our favorite services to offer along with Vintage TV servicing which seems to be the type of service most often requested.  Recently, we performed some Vintage TV work for a client in New York who mentioned that Jukebox Amplifier servicing is an area of Vintage Electronics servicing where demand exceeds supply.  So, while continuing to refer advanced servicing of cosmetic, mechanical, and selection circuitry to jukebox specialty shops such as , we at Amptech Systems are officially entering the marketplace in response to growth opportunities in Jukebox Amplifier servicing. All makes, all models; Amptech Systems offers recapping of the audio amplifier chassis of any jukebox equipped with a tube-type amplifier, whether stereo or monaural. Deposit and Estimate policies for jukebox amplifier servicing are the same as our standard Radio/Audio/Miscellaneous ($35 Deposit, typically one-week turnaround time from date of receipt of chassis to be serviced and completion of Estimate, one to four weeks for Restoration from date of Estimate approval under normal workload conditions).  To request Jukebox Amplifier service, simply select "Amplifier (Jukebox)" from the "Type of Set" menu when filling out the  Request Restoration form and provide contact and service request information as usual. If the Chassis Model Number of the jukebox is known, please include that number in the "Notes" section.  

Vintage Solid State Audio Servicing (Repair & Restoration) Also Available

We're adding Vintage Solid State Audio to our actively advertised Restoration services. The client who brought this Realistic STA-2300 only approved an Estimate for some basic repair work, but the project was a good start. We're ready to do Repair work, up to & including full Restoration, on items of similar type & vintage.

Your "Roundie" Color TV Headquarters    

We are one of only a few shops fully equipped for Color TV Restoration and actively advertising this service. 

All 21" Round-CRT Models and most Rectangular-CRT (Tube, Hybrid, or Early Modular Solid State Chassis) Models are supported by or Service Equipment

Pictured Above:

The "Roundie" models are a particular favorite of the Technical team at Amptech Systems / TUBETVSHOP.COM, the first Color TV sets we remember from childhood & the first Color TV sets we learned to service as Student / Apprentice Service Technicians.

Early Postwar B/W Models are another of our specialties. 

Our great familiarity with these early Postwar designs such as the RCA KCS-20 & KCS-21 & KCS-26 Chassis, RCA KRK-2B RF Unit (13-Channel TV Tuner), Dumont RA-103 through RA-113, and Mallory "Inductuner" (both the 13-Channel and 12-Channel versions) RF Units means that even the Restoration of sets in "rough" condition is often possible.


To our clients who intend to buy unrestored Vintage TV items via eBay which we will ultimately be Restoring, be certain to ask the Seller about making arrangements for shipping the set directly to our Restoration Shop for you.  We will provide Packaging and Shipping Insurance Terms-Of-Service Compliance instructions to Sellers at no additional cost for any eBay-purchased item whose Buyer pre-schedules for a Restoration Estimate with us during the completion of Shipping Arrangements with the item's Seller (Standard Pre-Restoration Deposit applies).  We will provide V.I.P. Service in minimizing the possibility of shipping damage and in supervising resolution of Insurance claims in the unlikely event that some problem does occur.  (Pre-sale photos of the item and photographic documentation of its Packaging will prove exceptionally helpful in verifying the item's pre-sale Condition and Insurance T.O.S. compliance of its Packaging).  We refuse to permit any valid Insurance claim to escape payment.  We are so certain of our ability to secure Resolution of any valid claim that failure to secure Resolution for any set known to have been packaged in full compliance with Insurance T.O.S. is the ONLY case in which a Pre-Restoration Deposit is refundable. (Deposit remains non-refundable in case of non-compliance by Buyer or Seller with Insurance T.O.S.)

Shipping Damage: An Extreme Case Saved by our Technical staff & Insurance TOS Compliance

We have even saved some sets after extreme cases of shipping damage over the years, but full compliance with Insurance TOS in packaging is critical for purposes of holding shippers accountable for costs associated with repairing damage clearly caused by rough handling in transit.

The 1949 Fada Model 930 pictured below is one example of an Amptech Systems success story. This set was dropped in transit, breaking its picture tube. Worse, the tube imploded on impact, large chunks of heavy broken glass propelled by about a ton of air pressure literally crushed nearby structures inside the set & some cabinet corner joints were split on impact.

  Packaged exceptionally well & shipped with adequate insurance, the shipper was ultimately held accountable & the cost of repairing the damage was reimbursed so that the Restoration involved no additional cost to the client. The set was eventually donated by the estate of its owner to the Early Television Foundation & is currently on display at the Early Television Museum in Hilliard, Ohio & accompanied by a plaque identifying the exhibit as a donation from the estate of a deceased client of Amptech Systems.

Attention Philco Predicta owners!  We have just completed documentation of a Philco Predicta Restoration and are ready to showcase that we offer Restoration for all models in the Predicta series and all conventional-cabinet models using chassis of the Predicta class (such as the Miss America and Slender Seventeener models).  View Dave's excellent article and photos here.

We now offer re-stuffing service for multi-section electrolytic capacitors.  Cost is $10 to $25 labor plus materials (varies by number of sections, capacitance and working voltage ratings of individual sections). Original capacitor units must be structurally intact (mounting ring and lugs unbroken).  Email Us to request a quote for custom re-stuffing of specific capacitor types.

We are also equipped to service Vintage Automobile Radio.  Service available for all tube-type and most transistor models, 6V or 12V DC, positive or negative ground.  Our Bench Power Supply can operate any Vintage Auto Radio for troubleshooting, alignment, or post-service testing.  We have serviced radios for 1937 Plymouth, 1953 Buick, 1963-65 AMC/Rambler, 1970-75 General Motors, and others.

Experience has shown that foreign sets typically require replacement of a far greater number of their original components during Restoration than American products require in order to obtain satisfactory performance.  For this reason, and due to a trend we have observed whereby foreign products typically require far more Labor during the debugging process, we have determined that Restoration of foreign sets is typically not economically feasible.  We will no longer accept Restoration requests for foreign items.  Limited exceptions to this new policy will be made at our discretion, but Labor rates and prepaid Deposit amounts for the servicing of imported items will be greater than those for American sets.
