About our Electronics Restorations for Vintage Tube Type Radios:


Each vintage radio repair we do presents many different challenges. Some are simple repairs, some are much more complex to electronically restore. Some sets that come in for repairs are all original, some have been previously wired incorrectly under the chassis by do-it-yourselfers that weren’t qualified technicians, and some were previously repaired by qualified techs back in the old days. In most cases, vintage radios have been worked on at some point in time and if mistakes were made, we can correct them using our schematics.

Our customers have presented us with everything from vintage “family heirloom” sets that have been stored away for many years, to radios they found at flea markets, garage sales, and estate sales. We have restored various brands of vintage radios manufactured by most U.S. radio manufacturers over the years for serious collectors and casual collectors alike. The costs involved restoring our customers sets vary widely, depending on the original conditions of the vintage radio sets presented to us for repairs. We have restored everything from museum quality pieces, to barn finds.

At Texas Vintage Audio, our focus is on the “electronics” restoration process of these vintage sets that range from early TRF circuit designs, to early and late model superheterodyne designs. While we have the expertise and bench test equipment required for the full electronics restoration process, we do not restore original nitrocellulose lacquer finishes or any major repairs to wood cabinetry of vintage radios. However, if the original cabinet is still in good condition and it just needs a bit of regluing and clamping to secure the joints for structural integrity, we can do that. We can refer our customers who are in need of vintage radio cabinet repairs to highly qualified professional restorers that specialize in these services if requested.  Most early radio chassis used cloth covered wiring. Many of these type sets will not need complete rewiring added, unless mice or the elements have destroyed the cloth insulation.

Notice about Rubber Coated Wiring used in Radio Chassis produced during the WW2 era:


Many tube radio manufacturers such as Zenith, Philco and several others used early type “rubber coated” insulated wiring when producing tube radios sets during the WW2 era. This type wiring replaced the earlier cloth covered type wiring for less cost to the manufacturers. These same manufacturers at that time were also downsizing some models of their metal chassis designs to produce much smaller portable radios such as the ac/dc powered Zenith Transoceanic hand held portable radio sets that soldiers carried to war. These weren’t the big chassis type home radios of the earlier years.

In addition, many other manufacturers were following design changes to lower costs and using this type rubber coated wiring in very crowded miniature chassis spaces. Most all of this old rubber coated wiring used is now brittle and hardened and needs to be either re-sleeved with shrink tubing or ultimately replaced. Our modern day wiring is not “heat sensitive” and will last many, many more years, as do components such as modern day “sealed type” capacitors. Manufacturers in those days simply used what they had available on their assembly lines to manufacture radios that people depended on for News and entertainment.

Today's modern components and new wiring insulation last much, much longer than the originals; however, the time it takes to make these necessary updates, as well as replace all the defective point-to-point rubber coated wiring in these old sets adds greatly to the amount of time in restoring these particular sets. Therefore, with this understanding stated, all prices quoted for safely restoring these type vintage radio sets with new point-to-point wiring is subject to a “case by case” evaluation. These repairs must be done before any new components are installed for safety reasons at added costs which vary depending on original conditions of the circuitry wiring overall.

Sometimes, a complete point-to-point rewiring of the original radio chassis is necessary to insure safety as well as years of dependable and reliable service. We do it right, or we don’t do it at all. No low cost electronics “patchwork” offered here. It’s not worth our time or yours. The only way to evaluate the cost of restoring vintage tube type radios is after our technicians closely inspect them on the workbench. After the initial inspection, we can then offer a price quote for a complete and dependable full electronic restoration.

Basic Electronics Restorations for our Customers Tube Type Radios Chassis’ includes the following:


1. Carefully clean the original chassis of dust and debris as well as close visual inspection of failed original electronics parts and any missing components. This inspection includes all transformers, coils, broken or shorted original tube sockets, original wiring, controls, switches, etc. and assess for any previous repairs. We can make any necessary corrections when applicable, which is verified by our in-house original schematic data. We can sometimes replace, as needed, some rare radio parts available from our spare parts donor sets. These salvations are on a case by case basis, or, we can search for these rare replacement parts when needed.

2. Check and replace all out of spec resistors and replace as needed. Check original field coil speaker status ( B+) coil windings when applicable.

3. Replace all capacitors including electrolytics, all coupling and bypass capacitors.

4. Check, test, and replace any defective or missing tubes.

5. Check for all correct operating voltages under the chassis once all new components are installed. We utilize slow up a.c. power applied with a Variac, while carefully monitoring voltages with all necessary bench test equipment.

6. Check original speaker for audio quality and replace if applicable. We can substitute for defective or missing original field coil type speakers if necessary.

7. Clean and re-lube all original controls or replace if applicable.

8. Check original internal factory loop type antennas, and make repairs when necessary if applicable.

9. Once radios are fully electronically restored and working properly, we "align” all radios according to the original schematics alignment data for best reception on all bands.

10. After all of the full electronics restoration is completed and aligned to original factory specifications, we bench test each restoration for a minimum of 12 hours to insure all of our efforts are stable and reliable just as when these radios were new, before returning the sets to our customers. We take pride in all our customers work, as we do in restoring our own vintage collection. We assure satisfaction in all our restorations, and stand behind our work.
