I have a pair of the SWTPC Universal Tiger monoblocks that need repair. I tried replacing the power transistors without success, surprise. Also, does anyone who repairs them also do any worthwhile mods? Thanks.
Checked the fuses. Serendipitously, my business partner got wind of a sound engineer who repairs vintage equipment 15 minutes from my house. I dropped off my CM Labs CC-2 preamp to see what he can do. If successful I'll post him.
