Electro-Harmonix Valves

[jimuc]

I am thinking of replacing the valves in my AC15Heritage with Electro-Harmonix.
Will the amp Bias have to be adjusted if I change them

Any help will be appreciated

Many Thanks
Jim

Jim like most if not all Vox amps there is no adjustment necessary for valve bias.

The AC15 Hereitage uses fixed cathode bias for the output valves.

Hi Jim, I replaced them in my AC15 Heritage with(El Harm) no problem, I bought them from Voc-rock guitars who were cheaper than Watford

Hi Roger and Keith
Thanks both for your prompt replies.
It's good to know that no adjustment is required.
Yes Keith I was on the Voc-roc website last night and their prices seemed very reasonable.
Once again thank you both
JIM
