    The ultimate DIY? A Stax SRM-T2!

    Ooof - then it sounds like you have some work ahead of you...

    So you only have one properly working side then?

    Sounds like current limiting in the power supply if only one side is powered up at a time and it powers up normally - 30r resistor to 25r or 20r will fix that. What happened though to cause you to start replacing parts in the amp section first - there may be something else afoot?

    I don't think so. He actually has a picture of a train and a picture of a bicycle side-by-side, and then goes on to state that they are not the same thing. I found that illustration particularly compelling. Though I think he might have had the arrows from the amplifiers pointing the wrong way...

    Only thing I learned from Fang's latest post is that a bicycle is not a train...

    Russian Mullards? Maybe you messed up the balance/offset process.

    Sounds like your tubes are the issue. If your tubes are within spec, you probably shouldn't have had to rebias at all. What were they measuring at before you rebiased?

    Well one thing in the earshock guy's favour is that Hifiman wasn't able to get him to be one of their shills - that's got to be worth something.

    But smoke and mirrors work wonderfully on their audience.

    It is just a link to a tutorial on caps : https://www.electronics-tutorials.ws/capacitor/cap_7.html (so you can better edumacate yourself, of course...), and the following Pf calculation: MOSFET C1=65 Pf Transistor C2=6 PfCtotal=C1*C2/(C1+C2)Ctotal=5.49 Pf

    The Board error is an easy fix - a missing trace if I recall. There are some posts on it in this thread. I seem to recall G600 had this issue. Why not post some pics of the sand (2sk216, 2sj79, 2sc3675 and 2sa1486) - sometimes it is easy to tell from a visual.

    Have a couple of these I've been meaning to get to. Wish I got in on the parts group buy as I just can't get motivated now.

    yeah but the rk50 is all gold-like and purdy lookn.

    First, it would be hard to prove (and to what end, now, 4 years later). Second, you would not have known, so you shouldn't have any guilt on your part. I corresponded with him back in 2015 about the Lil Knight T2 boards he was selling and he indicated that "Last time I heard from him was 8-9 months. At that time, he was in hospital, probably in a coma. He was a big help to me back then, not sure what happening until now." Maybe it is true. If so, prior to going into a coma Lil Knight gave this guy all his partially completed amp builds, audio parts, T2 boards and chassis parts to sell on Head-fi...

    You will need to move your PSU board forward to make space for the transformers. And have you tried fitting the amp board with the brackets? Might want to double check that it will fit (and whether there is space for you to use board mounted XLRs), looks like it from here, though (as long as the brackets line up).
