Golden Age Pre-73 Mk2 repair worth it?

[Mr. Pickles]

My trrusty Golden Age Pre-73 Mk2 has developed a 60 cycle hum coming in at about -38dB. Is it worth it to have a tech put it on the bench? The cost of labor might be worth more than the unit. Thoughts?

I've done some basic troubleshooting such as plugging in the power supply in different parts of my home and studio and through different power conditioners, but the result is the same. I've also swapped out mic/instrument cables but the hum remains.

Update. GA customer support was excellent. Sent for repairs and received already!

Did you only have to pay postage? You seem happy with how it went, so I suppose it didn't cost a lot.

I have an MKII with the same issue or so it sounds.
