Parts & Accessories

On this page, you will find vintage television items which are currently available for sale. Restored sets, surplus unrestored sets which will be available to buyers who may be looking for a do-it-yourself restoration project or an as-found set for display, and the Amptech Systems line of reproduction parts will be posted here. Working sets have been evaluated and restored to working condition. Unrestored sets are as found and untested. The purchase of a restored set includes a detailed report on its restoration listing the time and materials involved and the approximate restoration cost. Here are the sets currently available. Prices are for the sets to be picked up from my location. On-site demonstration is available. Shipping is available at additional cost. Preferred payment method is

for online purchases or cash at time of pickup. Ohio residents and out-of-state customers paying cash on-site are assessed 6.0% Ohio sales tax per current Trumbull County sales tax rates. Shipping Insurance is automatically included for the full purchase price on

purchases. Items weighing up to 70 pounds will be shipped via UPS Ground. Items larger than 70 pounds will be shipped via FedEx Ground due to higher FedEx size and weight limits.

Unrestored Sets

Vintage TV Accessories

NOTE: Accessories like the ones listed below were once sold in retail stores and readily available in virtually every town across America, but most stores no longer carry these items in stock and many store clerks are too young to remember what they are. If you've ever gotten that "You're looking for WHAT?" look from some teenage store clerk, you'll love that I'm offering a line of accessories that can be ordered from one convenient Web-based source. A $20 minimum order is required.

Parts Reproductions

Amptech Systems proudly introduces our line of reproduction sheet metal parts for vintage televisions. Quality construction and attention to detail are standard practices. We have a continuously-expanding line of parts such as back covers and high voltage cages. Here is our current line.

Media

The first product in what we hope will become a vintage television media library. I have approached the copyright owner of a true icon of the vintage television era regarding the purchase of a limited license to use his artwork for video transcoding to DVD in consideration of a licensing fee and royalties. Perhaps at some later time, we can work together on this. Until then, my camera and CAD software have been pressed into service (with many thanks to my friend, Jamie Ralston, for the suggestion and to Angel, the family dog, for the photo-op).

Mechanical Parts

We have established a working relationship with a Machine Shop specializing in "miniature" parts. Among parts which can be Repaired are Tuning Shaft and Detent assemblies for RCA models 621TS, 630TS, 630TCS, 641TV, 721TS, 721TCS, 730TV1, 730TV2, and 8TS30 (RCA part numbers 71463 and 72743 for RCA KCS-20 and KCS-26 chassis respectively). We had hoped to market actual Reproductions of these, however, we have been notified by the Machinists that prohibitive costs would be involved in reproducing the complex three-dimensional contours required for the Detent Plate part of these assemblies. Since failures of these assemblies rarely involve a need for replacement of the Detent Plate assembly itself, however, (typical failures involve Shaft or Spring breakage, parts which can indeed be fabricated and installed for reasonable cost), we will soon offer Repair Service for broken RCA Tuning Shaft assemblies 71463 and 72743 via a Machine Shop in our local area. Many other Control Shafts may also be candidates for Repairs or Reproductions. Email us for more information.

NOW AVAILABLE: Repair / Rebuilding Service for 1946-1949 RCA Tuner Shaft / Detent Assemblies (original RCA part numbers 71463 and 72743, as pictured above)

Do you have an RCA "Channel 1" set (621TS, 630TS, 630TCS, 641TV, 721TS, 721TCS, 730TV1, 730TV2, 8TS30) or "630-Clone" set (branded Air King, Crosley, Fada, etc. and obviously containing a chassis based on the design of the 630TS or 721TS) whose Channel Selector no longer "clicks into place" on each channel as the selector is rotated? Is the nonmetallic inner shaft broken inside so your otherwise-working TV has to remain perpetually pre-set to Channel 3 or Channel 4 internally? Have you grown tired of fiddling with the knob to "Find the Sweet Spot" where all six wafer switches inside make optimum contact? In many cases, a damaged Tuner / Detent mechanism has proven to be "that one last imperfection" needing to be corrected in sets for our own Collections. Now, after years of research, unsuccessful attempts to seek out any NOS replacements that might have been available, etc., we have found the solution to the problem!

RCA Tuner Shaft / Detent Repair (part number 71463 or 72743) starting at $79.95* plus Shipping

Request RCA Tuner Shaft / Detent Information via Email

* Quoted starting price is for repair of Detent portion of otherwise intact assembly. Straightening of bent parts, replacement of broken shaft(s), or correction of multiple problems may involve additional cost. Inquire via link above for more information. Repairs performed under subcontract by a Machine Shop specializing in miniature mechanisms (up to and including 1/4-scale V8 engines). Materials and workmanship are of such quality as to fully justify the cost.

Research & Development

We are currently developing a product which will permit true portable use of "Three-Way Portable" tube radios while requiring no modification of the radios themselves. Due to different battery voltages and configurations, these units will need to be custom-built for radio models having a particular original battery complement and will not be interchangeable with any radio model which uses types and quantities of batteries different from those for which the unit was custom-built. For example, a power pack designed to power a radio using two 4.5V "A" batteries and two 67.5V "B" batteries would not work with a model using three 3V "A" batteries and two 90V "B" batteries since one or more characteristics (voltages, battery plug types, physical size) would differ between the two models. Pricing is to be determined after market research. The design of the power pack will be such that the DC-to-DC module and the pack of "AA" cells which power the module and the tube filaments would fit neatly into the battery compartment provided within the case of the radio for which it was made. Our goal is to develop the product so that a custom version for any Three-Way Portable device using "Dry-Cell" batteries and having "A" supply demands of 1.5V to 9V and "B" supply voltages from 45V to 150V can be easily constructed.

Send an email with comments/suggestions regarding this product idea. Please include as much information as possible (battery-complement information, voltages, Eveready type numbers, quantities used, and/or make and model number if you have a specific set in mind for a custom-fitted power pack.
