First of all, hello everyone! I have been following this thread for the past year while I’m waiting for my Glenn OTL to be made. I’ve also collected some tubes for it recently. The seemingly rare Mullard CV1933 (6J5 equivalent) AMERTY I‘ve aquired recently says it was made in Canada. I’ve...

Please feel free to do so!:)

The Noir Hybrid HPC cable for my ZMF Verite was delivered to me on the first morning of 2020. Great timing! The cable is surprisingly light, and oozes quality. I couldn’t spend enough time listening with the new cable attached so I can’t say anything about how it sounds yet, but I’m already...

I’ve been using the PEQ below for a while now with the universe pads. My target was the HD650’s frequency response in this region. It’s not perfect, I’m still trying to get it better, but good enough for now. 1600Hz 2.6db Q=1.8 3200Hz 5db Q=1.6

I'd used a Saga to tame the gain on my TU-8200 for about a year, but sold it recently because I got a passive transformer to do the job. I did find that with some tracks it reduced the clarity a little bit. Even after upgrading various parts of the amp, I couldn't hear it with the HD650 but...

I haven’t heard the WA5 or WA22, but I’ve picked up a WA6-SE a few months ago with a WE422A rectifier and Westinghouse 6FD7 tubes in it. It is a very good amp, but directly comparing it to my modded TU-8200 (with Valvo E80CC and Hitachi 807 tubes), it looses in almost every aspect. The Elekit...

Yeah it maybe doesn’t worth the effort. I use about -18db digital attenuation in software and even with that I’ve got about 10-20% usable volume on the pot. Roon does the DSP in 64bit floating and then converts it back to 24 bit before output. (My Yggdrasil can’t do 32bit) Most of my music is...

Actually it would be fine to reduce only the gain of the headphone out. Is there a better way to do that? I have way too much gain.

I have a question. What resistor value should I use in R3 and R4 if I want to reduce the gain of the tu-8200?

Good to know! Thanks. About my rattling E80CCs: I’ve got a good deal on two used pairs of tube dampers in a local store. I hoped it would solve my problem with the driver tubes rattling a little. It turned out that the tubemonger socket savers made the rattle way worse. After removing the...

I’ve read that a couple of times but thanks for reminding me again. I do plan to build some kind of cage for it. I try to be as careful as I can be, I made a cable with a big resistor to discharge the caps every time I open the amp etc. I picked up 6 pairs of Valvo E80CC for cheap when I had...

I don’t know anything about electronics or how amps work and sometimes I wonder where did I find the courage to try to build an amp like this. (I think this thread was the main reason:)) I even had to but the screwdrivers and every tool new just for this project. So I messed it up a few times...

Unfortunetely I forgot to took pictures last time I opened up the amp, but I have some (bad) pictures from before:

Hi guys! I’ve been lurking in this thread for a very long time, this must be one of the most informative thread around here. It was a tremendous help building my Tu-8200 about a year ago, so thank you! It was my first build ever, I was learning how to solder on the way. I did some upgrades...

Sorry about the quality, but this is the only version available and I love this song. Felix Lajko and Magdolna Ruzsa: Még azt mondják
