Kat34 - Looking for someone to service/upgrade

[hogbenc]

Hi all,
I have a Kat34 which i built approx 20yrs ago and it's in need of some TLC beyond my skill level and time commitment!

I get occasional rustling on one channel and also excessive hum (again occasionally) which i'm guessing is an earth problem.

I'm also aware of various upgrades that have been suggested over time.
So any recommendations/suggestions for someone that could take a look?

Thanks,
Chris
