Thanks Willy, This particular amp is very easy to overdrive, 50 watts will produce 1200 watts output. 73 David N1EA ----- Original Message ----- From: <K3vw at aol.com> There usually is an adjustment for any ALC. It may be internal, if not external. ALC is not always needed in a grounded-grid amp. I never use it in mine. Willy K3VW ----
