Hi all,
I just picked up a working Acoustic Control Corp. 135, which is the 150 head with 2 x 12 config.
Other than missing the cable wrap lugs on the back, scratchy pots and some cosmetic bumps its all working including reverb and tremolo.
Since this is about a 1974 vintage I was thinking of replacing the filter caps.
Anyone have an estimate on a cap job for a 134/135 or 150 head?
Other restoration tips?
Thanks
Hi @markustg - welcome.
Unless it's humming excessively, I wouldn't bother.
If you do it yourself then it's just the cost of the caps, otherwise you'll have to get a quote from an amp tech - rates vary.

It's not just filter caps, it's ALL electrolytic caps that have gone bad.
But I second the opinion that I wouldn't bother unless the amp is obviously showing signs of aged capacitors.
