And here is a more in depth video reverse engineering one of those amps.

EEVblog #837 - Reverse Engineering A Valve Headphone Amplifier

Whilst an interesting video - my word this chaps voice is irritating in the extreme! I had to watch this in 3 or 4 minute chunks spread out over a day. I could not contemplate watching the rest of his videos, no matter how interesting they may be!  :headbanger:

That is some serious turning. Can't believe how solid that lathe is with 600lbs of unbalanced wood spinning @ 100rpm.

Yes it's crazy! And in the end of the video the guy mentions that the customer didn't even use it, because he (the customer) soaked it, against the turners recommendation, in some finish that had a bad odour.

If you are interested in vintage valve guitar amplifiers I recommend the entire following YouTube channel:

Uncle Doug
https://www.youtube.com/channel/UCuR4hQTXkG_KxozLxwPzEjQ

His videos are very thorough. I've linked to some of his videos in this thread before, but honestly his whole channel is worth a look.
