Funny thing,
That #29 dual cap that bypasses the hum bucking trimpot in the filamen supply says "dual 0.25uF".
The sch shows them each being 0.5uF.
Whn measured one was 0.46uF and the other 0.64uF.
This is closer to 0.5uF value but then these caps are known to increase in value when ageing.
I fgured this is not overly important so put in two 0.47uF.
I decided not to open tnis dual can as it involves unsoldering the seams and this is unnecessary: done that to a can in AK808 but then there was like 6 caps in there.
I hid the two behind the can so they are not readily seen.
Tomorrow will attempt to open the large can. I did that before with 111 chassis and that wasn't too bad: I didn't scrape it much or warp it and was able to keep the terminal board. With some luck I could repeat it.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
