Hello AKer's. I picked up a 2220B off of CList today and here is what I found:
No sound on any mode
I pulled the output transistors for testing and they all check out as being OK.
I use the manual to verify that the transistors are in the correct position
I plug in and power on and the amp smokes and the fuse blows instantly
Is the manual incorrect?
My understanding is that the location should be:
H001 H004
NPN NPN
D188 D188
H002 H003
PNP PNP
A627 A627
Is this correct? I am kicking myself for not paying close attention but my excitement got the better of me
