Voltage Change for Jeff Rowland amps?


I was wondeirng if voltage for the older JRDG amps (model 6/8/9) can be converted easily. If not, would it require an extensive overhaul?

Thanks in advance for the advice.
Look first at the Jeff rowland web site in the section for classic amps:
You should be able to download documentation for the amps you are interested in. If you do not find voltage conversion information, you may need to contact JRDG.
