Groove N Tube

Restored Record Players and Radios from the 50's

The Groove N Tube Restoration Process

Groove N Tube restored Phonographs and Radios are from an era when electronics were built to last. The early to mid 1950’s

It is the mission of Groove N Tube to bring them back to their full glory, so they may be enjoyed for another 50 or 60 years.

Back when folks weren’t so antisocial with earbuds stuck in their ears, or busy texting their BFF,  it was a time that perhaps your parents, or even grandparents may have listened to a ball game on an AM radio in the garage or while doing chores. They may have had a collection of 45 phonograph records with artists like Buddy Holly, Elvis, or Fats Domino.  Playing a stack of ten or twelve 45’s on the phonograph might not seem like a lot, but the enjoyment was priceless. 

Let me explain a little about the technology of the time…

Typical Tube Radio Schematic


GE 424 Schematic w/ Safety Caps

This is an example of an all-American 5 tube set tubes.

Certain Capacitors in Radios without a power transformer should be Safety Rated.

Those that are across the AC line as is C10 can be X or X/Y-Rated. These would be flame resistant.

Capacitor C4 must be a Y-Rated since a short-circuit could cause lethal voltage to be present on the main chassis and exposed metal parts.

Suitcase Style RCA 45 RPM Phonograph. This model 6-EY-3A has a tone control , not found on a lot of 45 players.

It can be played, and even sounds better with the lid closed.

Little Marvel Microphone

Karaoke in the 1930’s! The Little Marvel Microphone was a microphone accessory to hook up to your radio or phonograph. There were two wire connections that were made to an amplifier tube’s pins. You could then sing or talk through your radio/phonograph while it was on and playing.

Motorola 58L11

Motorola 58L11 AM Radio

Motorola 58L11 AM Radio


This Motorola 58L11 is a four-tube AM radio and is dated June 18, 1948. It’s old enough to collect social security payments!

It’s been freshly restored and aligned with new capacitors and several resistors that were a little wonky (technical term).

The case has no chips or cracks and has minimal scuffing for its 65 years of longevity.






The RCA 7-EY-1JF Phonograph is often called the One-Tube-Wonder since it uses just a single tube for amplification.

This 1956 record player might not get quite as loud as some other players, but it plays really well and sounds fantastic.

It’s a real treat with the mid fifities Gray and Salmon-Pink color scheme. Again a full restoration ready for years of service.



RCA 7-BX-7 Radio

RCA 7-BX-7

RCA 7-BX-7

The year is 1957 and chrome has gone mainstream. The gray and chrome remind me of the grll of a mid 50’s Ford Crown Vic!

Older radios sometimes had to be turned to get a strong signal, not with this radio… it has a swivel antenna.

Instead of a dial cord and pointer, a vernier dial is used to fine-tune the stations. The outer ring of the dial rotates about 3-1/2 turns to tune from one end of the dial to the other, much like a steering wheel in a car.

The RCA 7-BX-7 is an AC/DC/Battery Portable Lunchbox Radio. As with most of these tube AM radios, the high voltage batteries are not generally available, but can be made up of a series of 9-volt batteries. And of course, it operates on standard 120 Volt AC house current.


Stewart Warner 9162D AM Radio

Stewart Warner 9162D

This restored Stewart Warner looks almost good enough to eat!

It is a clock radio, and both the clock and radio work like a charm. There is a light behind the dial that rotates with the tuner to give you an indication of the station you are listening to. It was built around 1953 with its unique design.
