Price drop on remaining tubes. Don't sleep on the Brimar and GEC 6V6G! Cossor (UK) 52KU fat bottle (same as U52; this one is super rare and beautiful)......$380 GEC (UK) 6V6G (pair) (gray glass)......$200 Brimar (UK) 6V6G (pair) (black glass)......$200

Mazda 12AU7 sold.

*edit* Added two photos showing superficial damage to the right rear corner of the amp. This happened during shipping to me. I will package it to survive the apocalypse, however.

I don't take the decision to list this amplifier lightly. I've weighed this for about 6 or 7 months. I've come to the final conclusion that I will not use this marvel much anymore and while I love looking at it, I hate that it sits idle not being enjoyed. It deserves to be used frequently...

Selling down my collection of spare tubes. Here are some of my best 9-pin noval base preamp tubes. All test NOS: 12AU7 (ECC82) Mazda France - 2-mica, gray plate, copper rods...............................$80 each, $150 pair SOLD ECC81 (12AT7) Mullard UK.............................$30 each...

Long shot here, but does anyone know if the 5CU4 rectifier will work in Telemachus? I'm trying to gather tubes to package with my amp for sale, but I would rather not include my expensive Cossor 52KU / U52. I have a 5CU4 leftover from my Glenn OTL.

I've vascilated over this decision for some time and have come to the conclusion that I will be selling my Telemachus soon. I just don't use it much at all now that it's been switched to integrated amp duty on my turntable rig. I haven't used it as a headphone amp in over a year. It is too...

GEC U52 rectifier sold. Second pair of Sicte 6L6G and Ken-Rad 6L6G are sold.

Thanks. Still, $450 a tube for A2900...wow. Can't say I disagree with the premium price though. They really are amazing.

I just listed some Aegis-compatible NOS power tubes and rectifiers in classifieds if anyone needs something.

*edit* Ken-Rad photo added. One pair of Sicte / Fivre sold.

Selling some rare tubes I had stashed away for future use on a new custom amp, but I'm going a different direction. If you just bought a new ZMF Aegis and you're ready to supercharge it, you've found the right thread. All have been tested and are near or above 100% and confirmed good on my...

Lol, I was just about to say that is a really high price until I saw the price of the A2900 in the case in @Mumbles06 Hong Kong picture. Is that $3500 USD???! I knew these were rare but dayum! Here's what Brent Jesse has to say. I have both types. 6060: This rare tube is the Brimar answer...

Sitting here listening and gushing over my pair of GEC A2900 triple-micas in my Quicksilver HPA just imagining how sweet these tubes are going to sound in a Velo...:thinking: For those that already have one, which power supply option did you choose? Has anyone tried it with both the stock and...

Looking forward to getting a Velo sometime later this year. @JacobLTA , in this circuit which affects the overall sound signature the most - the preamp tubes or the power tubes? I've been building quite a collection of rare top-tier NOS tubes to try with this amp.

Wowza! Glad to see you post again, Glenn! If you'll build me another amp I'll come and pick it up right off of your workbench. No need to lift it into a box! :wink:

Special price on a spare set of these that I have. The GEC A2900 is as good as it gets for the great 12AT7 tube. This pair is the double-mica ring getter version. Manufactured in the Hammersmith factory in November 1972. Tested and guaranteed quiet. I'll offer a 1-week return if you don't...

Headphones and cable are sold, thanks.

I found this picture from two years ago when I first got it. Look at how the Tele dwarfed the Glenn GOTL I had Lol. By the way, my amp is the first Tele built and is the one shown on the website in this picture. RIP Tomas :disappointed:

Thank you! Finding matching quads was the hardest part. By the way, for anyone that's interested The Container Store has neat display boxes that can be modified to hold tubes.

Here are a couple photos showing examples of my 6J5-family tubes. Running quads of these in the Telemachus will give me any sound signature I'm in the mood for. Admittedly, I mostly use the GEC L63 or Raytheon engraved base tubes. From left to right: GEC L63 (early Cossor branded, marked as...

Thanks. I made those from Hammond project boxes and Belton sockets. They're overbuilt for the purpose but look cool, lol. Yes I'm exclusively 6J5/6C5 on the Telemachus. I'm sold on the concept of using dual single-triode preamp tubes in place of one double-triode tube. If my Sparkos Gemini...

This is a beautiful headphone in very good condition and is very comfortable. It pairs well with tube amplification and scales nicely with higher end equipment. I just need to clear out some gear hence the sale. The only blemish of note is near the gimbal as shown. Comes with the Auteur...
