Admiral 5D4 Model 275 AM Tube Radio – SOLD

November 18, 2010

This one is about as good as they get, almost immaculate

Admiral 275 – 5D4 American 5 tube am radio in Red. Made in 1958.

The Good:

This radio has been Restored with New Electrolytic Capacitors. All the tubes have been tested on a Hickok 533. it was completely dismantled and washed in soapy water to remove all dust, the chassis was blown off with compressed air. the outer case was buffed with auto polish to remove any surface scratches, and as you can see it is shiny. there are no cracks and all places where the chassis is screwed into the plastic are solid, and the screws are original. The power cord is in great shape. The gold foil with the stars is shiny and in good shape.

The Bad:
The grooves in the tuning dial and volume knobs still have some grime in them (I didn’t want to damage the gold center caps) and the dial above the “6″ has a slight scuff

The “A” and “L” in the logo has a very small amount of the gold plating worn off.

the grill is 99% perfect, except for some slight discoloration due to age.

Price – SOLD

History:

Here is some history of this fantastic amp:

“In 1959, Marantz released the Model 8. With the soon-to-follow 8B, it was the only tube stereo amplifier the company ever produced. Although most regard the Model 8B (introduced in 1962) simply as a modified Model 8, there are significant differences between the two. For one thing, the 8B featured a Sidney Smith-designed transformer, and was more stable and phase-accurate, thanks in part to a negative feedback circuit originally developed for the Model 9 monaural power amplifier…… The power output of both the Model 8 and the 8B was 30 watts per channel.” – click here if you want to continue to read about the history of marantz”

Here we have an extra clean original Dynaco ST-70 Tube Amp, with cloth transformer leads,NOS dynaco branded 7199 Driver Tubes. a NEW Sovtec 5ar4 and a matched quad of Electro Harmonix el-34′sOverall Electronic Condition :
Amp has had 2 caps changed on the driver board; and were replaced with matched orange drops.on the underside of the amp you can see there is some slight discoloration on the bottom of the driver board from the heat generated from the 7199 tubes,
Also you will see a small amount of wax that has leaked out of the choke transformer, it has no effect on the discoloration.

Build Quality:

  • Since this is a Kit, the build quality is top notch, all heater wiring was routed in the correct way and twisted to ensure quiet operation; the layout was done correctly and the soldering looks very professional.

Appearance:

  • The lettering is all intact, and the chassis plating is in VERY good condition with slight pitting by the center power transformer.
  • The bottom as a few scratches and as you can see from the photos the rubber feet are missing.
  • The Tube Cage is clean; however there are a few scratches on the top surface, as well as a few minor paint chips.

Tubes:

  • The NOS 7199 tubes test Very Good / Strong + on my B&K tester(100 is new and these test 98+)
  • EL 34 tubes have about 20 hours on them and were purchased as a matched quad, they hold bias well.
  • 5AR4 tube has also about 20 hours and tests strong / new

Sound:

  • This is my second ST-70 and by far the better sounding, it also is the most original, I have played it using a Dynaco PAS2/3 preamp with an audio lab dac and the sound is fantastic, transparent and clean, it can compete with my vintage Scott in clarity and warmth. overall this is a great example of vintage American Tube Technology from the Golden Era of HiFi.

Very Vintage Kay Guitar Amp – SOLD

April 9, 2010

Well it is time to let go of some gear, and this is the first piece to go. we have a very vintage KAY from the late 30′s to mid 40′s since I can’t find another one anywhere on the web I have no way to date it.

What I do know is the following:

  • The 6n6 tube was first manufactured in 1939 so the amp must be from after then.
  • We have a field coil speaker which means that it was probably earlier than 1952 or so because that was when they were able to produce magnets that were strong enough and affordable for speakers
  • The covering of the cabinet is made of the same stuff early aircraft were covered with
  • The soldering was very well done so it is probably post war since there was a rather high demand for electronics after the war and there were a lot of trained electronics assemblers that needed work

If anyone knows any more about this very cool and good sounding amp please feel free to contact us.This small amp produces about 4 watts of power and has been restored and upgraded with new caps, and a 3 prong grounded cord. The buyer will receive the original caps and all the other “bad” parts that were removed during the restoration.
