Paul Gryzbek was a fine fellow, and a wiz with the tube gear. He brought many a Fisher 400 back to life, and made available to the masses good sounding tube gear that didn't cost an arm an a leg! I owned of his Cayin TA-30 amps with Bizzy Bee upgrades in the past and enjoyed it very much. It is really sad that he died so young.
Hopefully there is someone here in the know... someone who can help get the preamp repaired for you. Maybe there is a stock of parts somewhere for your TAD 150? I believe his widow is named Kathy, there is a chance maybe she could help. I will be looking around on the net to see if I come across any leads. Love to see the 150 playing music again for you sonicsoul and that is certainly what Paul would have wanted. Can anybody help this gentleman with a transformer?
