David,
Feedback much appreciated...
I have quite a few of these, not the TK27 though. The voltages of the HT is close to 270v after changing the old rectifier..
Prior to changing the rectifier the voltage under load with all valves was 220v, now at least its up to 242v under the same conditions, but no where near the 260-270v
I am wondering if the new main filter caps put in are the problem, as i have always put in the much larger guitar amp caps, not these little ones, though they are rated to 47uf/400v.
Have not tried recording yet, playback is very low, about 10-20% of normal. Will try play again, after the new rectifier was installed.
