Title: Dodd Battery Pre-amp and Amp repair in Los Angeles
Post by: abernardi on 28 Jan 2018, 06:10 am

Hi all!  I know this isn't strictly GR related, but I also know Gary was near and dear to many here.  I have two pieces that need some work:

1- Battery powered Dodd Pre-amp, the right channel is cutting in and out.

2- Battery powered 15wpc Dodd Amp - won't light up at all, bricked.  My guess it's that tricky power supply.

Anyone know of a technician who could help me out in the Los Angeles area?

THANKS!!

Adam

Adam,
Some things the tech will want to know.

1) Is the volume cutting in/out as you change it?  Or is it doing that one its own?

2) Gary's battery amps used a 6VDC regulator IC for the tube filaments and not the HV supply, so it may not be as bad a repair problem.  Have you checked the fuse?

1 - It's doing it on it's own.
2 - That's good news.  Yes the fuse is OK, but I'll check again.
