i just got this amp for a few bucks. the guy tried to have it repaired but that didnt happen. this is the worst i seen so far.also do anyone know what these two smd parts are?

 

[Perry Babin]

Which two (circuit board designations)?

 

[timwebb]

c152 and c170 on the sides of the resistor in the first picture

 

[Perry Babin]

They are ceramic capacitors. The value is likely 1uf but that's just an educated guess.

Hi Perry!

Good Day! I have this kind of amp...do you have an idea why my amp has a hizzing sound? I replaced the L500 output inductor, do I have bad filter capacitors?

I think the problem is that someone added too much solder and now all the pins on the transistors are making connection.

 

[timwebb]

yea they messed it up bad. its done now. and playing

So give us a list of what you replaced and had done inorder for it to work.

rebuilt the power supply replaced a few diodes near the drive transistors. and changed a few output drive transistors.
all i can say is mr perry is the man!
