Title: Crate v100h replacement power supply
Post by: Tamastarclassic on March 07, 2020, 10:14:29 pm

I am the unfortunate owner of a Crate v100h head amp. The power supply blew q1' q2 and associated components. Does anyone know what I can do with this amp?
I don't trust a smps at all. Can you use a power transformer in place of the switch mode power supply. I have been an Electronic Technician for about 25 years. I Repaired Tv's back in the 90s I understand the power supply. Consist of 5 different supplys +420 -63 +15 -15 and +12.6 I hate to just junk the amplifier.
