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.
Up for sale here is this pair of used vintage 1949 250k ohm linear taper potentiometers. I don’t know who made these–each is marked “4-62, ” but that’s a part number, not a date or EIA code. These have short 1/4 round shafts. They test around 271.9k ohms and 254.7k ohms, so fairly close. These are very r are potentiometers and will work great for you, though they may need some Deoxit. These are for amps–they are probably too big for a guitar. Please see my pictures for details. If you have any questions, please ask. I have more potentiometers and other vintage electronics listed–feel free to take a look!

Here we have a pair of pair SIEMENS 1950 VINTAGE MONO tube amplifier, type: SF V6.6. This is possibly the most famous and best type of the ” green ” series. Multivoltage 110/220 Volt AC. 2 x EL95 In Pushpull (PP) mode. EF86 for low noise input chanel and T42 Input transformers (also very famous for Denon MC step up transformers). The price is for both!
This is for the pair of Ampex 6L6 amplifiers as shown. They do not include any tubes and will need tubes. One of the amps appears to have had the capacitors replaced and a wire cut from the switch and the fuse. I’m not sure if this has been bypassed for some reason and perhaps that’s why this was done. See photos for details. Physical addresses only no PO or apo boxes.
The McIntosh MC60 is a highly esteemed pair of mono tube amplifiers that deliver 60 watts per channel, known for their robust construction and exceptional audio fidelity. These amplifiers are celebrated for their ability to produce a warm, rich, and detailed sound that is quintessentially tube-like, with a smooth and natural character. Each MC60 unit features a push-pull design with large transformers that ensure stability and enhance the amplifiers’ ability to handle complex loads with ease. The design also includes McIntosh’s renowned feedback circuitry, which minimizes distortion and maintains a clean, clear output across a wide dynamic range. The front panels are classic McIntosh making them as visually appealing as they are audibly. Ideal for driving a wide array of high-fidelity speakers, the MC60 amplifiers remain a coveted choice among audiophiles who value the timeless appeal and superior performance of vintage tube amplification. We don’t just power test our units and then write “tested, works” in the title (like a lot of other sellers we see). We usually always include a video unique to every item for you to see for yourself (for working units). Apart from that we put work into every unit, specializing in cosmetics which ranges from cleaning pots/switches to polishing the windows on receivers and conditioning the wood on wooden cases and speakers. In good cosmetic condition, has some scratches/marks, see pictures for details. Unit has been cleaned all around to remove as many blemishes and dirt as possible. Silver base has been polished to remove some light scratches and increase the shine. Only comes with what you see in the pictures which includes the unit itself only. Unit has been fully tested and works great for the most part apart from some red plating on one of the amps which can be seen in the video demo. This might be a very simple fix and the unit still works. One of the output tubes on the second to last picture has a broken orientation base but still works. They have been marked with black marker to show you which way to place it in (place it in facing the silver mcintosh logo). Above you’ll see both units pictured separately so you can see exactly what you’re getting with detailed pictures of each. Both units come from a retired vintage HiFi store owner who took good care of them. See video above for demo. Upon purchasing this item you accept and agree that you have reviewed all of the pictures and understand that what you see is what you are getting. This also means that despite what we wrote in the description if you see (or don’t see) something in the pictures we didn’t mention or we missed, the picture should speak for itself at that point. If you have any questions please message us and we will be happy to respond to your questions/concerns. To avoid confusion, this does not specifically mean that this item is an “as is” item unless stated in the description above.
