London Power - Power Scaling with SV1 and RBX (Fixed Bias)
Have you tried this Power Scaling solution? Post your questions or comments!

London Power's Power Scaling Kit for Fixed Bias (SV1) and their Raw Bias Auxiliary Supply Kit (RBX) are almost always used together to achieve Power Scaling in 99% of guitar amps. Check the SV1 product page to see if your amplifier is one of the 99%. If in doubt, contact Kevin O'Connor at London Power:

The Raw Bias Auxiliary Supply Kit is typically needed because the amp's original supply is not robust enough to support Power Scaling. Does your amp need RBX? See this article to check: When Do You Need RBX Raw Bias Auxiliary Supply?
