Default Re: Musical Fidelity B1

Wow!
Now this is what I was looking for!
Got my B1 somehow biased with the aid of an italian forum last spring, but I see now there is still something to do.
I just found a german company which offers paired 2N3055, so I might buy some and try to adjust my B1 in March.
Some years ago, I had to replace the transistors 15-18 with newer types, after the amp blew.
I cannot read the handwriting so well, what are their names?
I would like to buy the originals again, should they also be selected/paired?
Last year, I tried to find a replacemet for the B1, but was always disappointed. The worst experience to my ears was a MF-A2, which sounded too sharp compared to the B1...
So, got this amp for almost 20 years and I guess, it will run the next 20 years.
One backdraw seems that my B1 clips too early for 32W (around 10 o´clock
on the volume knob.)
BTW, the AC Voltage from the transformer is about 25V?
All the best,
Salar
