My Crack Smokes [solved]

[Paul Birkeland]

Can you post some photos of your build? 

 

[captain widwiki]

I've soldered and resoldered many times so it may look strange in some places

Your hum is probably MJE350 related. See this thread:

Edited To Add:
Have you tried using a 6080 instead of the 5998?

 

[captain widwiki]

It's not a hum but a loud buzzy noise, and I don't think my 5998 have any problem cause within the stock building he is dead silent.

 

[fullheadofnothing]

But have you used the 6080?

 

[captain widwiki]

Yes the first month but I've changed because my 6080 was noisy

 

[Hornet900]

when I plug the jack (without source) there is a loud noise in both channel (but louder on the left). This buzzy noise is louder when the volume pot is at 0 and decrease at higher volume (but is still louder than anything i've heard). There is also a scratchy noise when I increase the volume the first time but not each time I touch it.

sounds like the problem I had captain ...try replacing the  MJE350 on the 2 small pcb boards, I bought mine from ebay  and solved the problem

Yes, replace the MJE350s. We got a bogus batch several months ago. We can send you some replacements. Just email replacementparts at bottlehead dot com with your request and shipping info.
