Acoustic Control Corp 135 care and feeding

[markustg]

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.

I was thinking of replacing the filter caps.

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.
