Vintage Tube Amp

All our tubes have been tested for. GAS SHORTS TRANSCONDUCTANCE & EMISSIONS. These tubes have been tested – and are considered NOS ; they meet or exceed the published data set for GM. NOS tubes fall within the Gm characteristic range of an average tube, as published in the RCA RECEIVING TUBE MANUAL, which states Individual tubes, like any manufactured product, may have characteristics that range above or below the values given. Test Results are ALWAYS available upon request (if not photographed). Send me a message! I might have what you need! Tubes will be packaged in white boxes – if the original boxes are not photographed in the listing or stated as “with original box” they are not included. 90 % of our tubes are Tv7 tested, our tv7 is Calibrated and our go to tester. The tv7 tester has been around a long time and is a trusted tester for military, who had high standards for reliable tubes that would not fail in critical conditions. Military standards were tubes needed to meet 60/65% which they established as (minimum value). There isn’t a “specific” indicator or result or data set anywhere that universally designates a vacuum tube as “new old stock” when using a tester nor for what test result is given. The best way is to calculate the GM – and check the data sheet for each tube – a “nos”tube should typically measure between the average and maximum micromhos(GM). A common misconception of tube testing is that every unused tube, new or vintage, should test at 100% of the meter scale of the tester. A tube was considered acceptable/new/ passed standards if it tested between the specified minimum and maximum on a tube data sheet or the minimum value specified on the tester (tv7 is minimum is 65%). Tubes do not give the same reading across testsrs – even the same model tester will give a different reading sometimes. If you don’t like the sound of a tube, so long as it is still in the same condition as arrived message me. I DO NOT OFFER A TUBE ROLLING SERVICE, vintage audio tubes typically require a burn in period, that’s where the tube sounds the best. Please see my notes on noise tests below. We have a few different testers available to ensure the quality of the tube (as some tubes can not be tested on the tv7). Tv7 testing is tedious and I spend hours testing tubes and double testing tubes – if you notice a mistake(like a picture doesn’t match the title) please be gracious and let me know. UNLESS PHOTOGRAPHED WITH THE ORIGINAL BOX- tube will come in repackaged white boxes- 50-90 year old cardboard packaging doesn’t hold together well, not in my hands anyways. We have over the last 20 years amassed a huge collection of vintage amps/ parts / tubes and have decided to downsize that collection. Every tube has been marked for tracking and security purposes – these marks wipe off easily and without the mark no return will be accepted. Sound quality is tremendously SUBJECTIVE. Tube tester NOISE TEST. This is a very marginal test, only for special checking. This test needs sound amplification; hearing / listening to noise with headphones would indicate a real disaster inside a tube (THE shorts test WOULD already BE evidence OF THIS). There is nothing wrong with performing that noise test however. That test is not going to tell you whether the tube will be silent in your SET (single ended triode) amp or in anything else. Ultimately, the best way of testing a tube for microphonics is in an actual chassis or amplifier similar to one in which it is intended to be used. Since amps have a wide variety of circuit designs and tube placement, this test is most effective in YOUR AMP or one that is almost identical. Hence, most people advertising tubes as tested for Noise or Microphonics are probably NOT testing them in any meaningful way FOR YOU OR YOUR AMP. “Noise” and “Microphonics” are often buzzwords for other issues. There is a small percentage of tubes that have a problem with noise but far less than most people think. In properly designed circuits objectionable “tube noise” is seldom found. In other words, it is a rare tube that will be noisy when used in most circuits. Always check the data sheet of the tube you plan to use. PLEASE message me BEFORE you open a return. PLEASE NOTE: Tube silkscreen (lettering on the tubes) is VERY fragile. It can be wiped off and destroyed VERY easily.

This is a Vintage 1967 Silvertone Model 1484 Twin Twelve 2×12 Guitar Combo head and cabinet. Silvertone was a trade name of the Sears, Co. This amp was made in the USA by Danelectro. Date was determined by the codes on the two matching original Jensen C12Q speakers (220708) and pot codes (1376701). All the tubes are branded Silvertone and original to the amp with one exception. One of the 12AX7 tubes is a Silvertone from my personal stash. The three preamp 12AX7′s are made in Holland, so Bugle Boy Aperex tubes branded Silvertone? All USA, and HOLLAND made tubes, that test strong on my Hickok 6000a tube tester. This amp is nicer than most of the 1484′s I see for sale. TREMOLO and REVERB, BOTH WORK. The speakers have been professionally reconed and probably do not have 10 hours of play time on them. One of the tube sockets has been replaced (reverb driver). This thing sounds incredible. EVERYTHING works and it includes the footswitch. Clean controls, no scratchy pots. The reverb is just as wild and wacky as everyone says about it. AND YOU GET TO HEAR IT FOR YOURSELF. This amp is so original, the speaker cord is still attached to both the head and cab. That is the first and last time it was serviced. This is an attic find that cleaned up very nicely. There is evidence of deterioration, but for the most part well preserved. Please look at the pictures for condition. Normal aging and patina. One of the knobs has a chip. You can take this out to play a gig the day you get it. As a basic test I have operated this amp for at least 4 hours recently and it did not fail, smoke, throw sparks, blow fuses, start on fire, etc. Old electronics are scratched, worn, chipped, cracked, dirty, dusty, stained, ugly, tinkered with, missing parts, etc. The exteriors have wear that includes cuts, holes, tears, scuffs, missing stitching, missing or replaced feet, handles, knobs. In the course of servicing over the years, they typically do not have all original components. Old electronics typically hum and have scratchy controls. Old electronics can fail at any time. This is part of my estate. LOOK AT ALL MY LISTINGS!!! The following is common sense stuff, but needs mentioned. You should not have to live with something you are unhappy with for any reason. If you alter, modify, change or “repair” the item in anyway without my consent, you are accepting the item “as is”, at the price paid. We will work through the claim together until things are right.

Very Cool Rare 1940s Vintage Silvertone Model 1300 Tube Guitar Amplifier. This has been sitting unused for many years. I do not have a VARIAC so I have not plugged it in to test it and possibly screw something up in the process. Given its age it would be prudent to have it checked over by a tech before use. I do not know its life history or if it had ever been modified by a previous owner so I have provided several photos of the interior so you can see for yourself what is behind the covers. Looks good for its age – needs some adhesive on some of the loose covering over the wood frame and a bit of interior dusting. According to the catalog, the 1300 was rated at 8 watts undistorted, with 12-14 maximum output watts possible at the cost of a slightly distorted sound.

All tubes and rated between 5-8 Watts a great little amp for recording or to use at home.
