First of all, congratulations! That's terrific that it's working again. Those Jensens probably aren't hurting anything, but the Rifa X2's have a very bad reputation for blowing. Might be better to remove those. Replace them with a modern film cap or just leave them out. I assume they're there to smooth out the diode switching noise, but I doubt you really need them.
Better check this out. Turn it up. You're listening to just the two small PSB speakers. Nice to have a single ended triode amplifier like this running again after 20 years! Any requests?

Congratulations on having your Woodside repaired. I was very pressumptuos when I told you that mine hadn't broken in 25 years. One day it stopped working but fortunately it was the fuse box that broke, probably when I took out the fuse to inform you of the value... Ugh! Simple to repair.
If one day you have time, I would appreciate it if you could explain to me how I can adjust it.

Of course! I've attached a few photos of the procedure. You'll need a small flat head screwdriver an an inexpensive multimeter. Set the multimeter to measure millivolts, (mV) insert the red probe into each of the 2 indicated openings where there are test points down inside and the black probe on any ground point... a screw head will do. Adjust the 2 potentiometers, indicated by the location of the small screwdriver in the first 2 photos, to achieve 70 mV at each test point using its respective potentiometer. Mine are set at about 65 mV. Easy peasy!
Just be sure not to allow the red probe to touch the chassis while in contact with the test point. I don't know if would be problematic but try to avoid it if possible. Some electrical tape around the probe, except for the tip, might save you some grief.
I'm curious what your readings are after 25 years!

Thanks for your explanations. I bought a simple multimeter and it is already adjusted. One channel gave between 56 and 59 mV and the other between 78 and 80 mV. I have left them at 65 mv. I hear it just as well, perhaps the low hum of the amplifier has been reduced. Now we have to find out how many Woodside SET 30 there are. Out of curiosity, did you buy yours on eBay in Germany?A Stereophile review of the Woodside SC26:

I have an old Audible Illusions 3A preamplifier as well. I'm not sure yet which I prefer.
