I have an Ampeg SVT-CL head on my bench that's making me scratch my head. When taken out of standby it has a loud buzz that lasts for about 2 secs then fades away. The amp plays fine and is quiet until the next time it's taken out of standby. Makes no difference if the volumes are at min. I put a plug into the main amp input jack to eliminate the preamp section but it still buzzes loudly at turn on. The only thing that will make it turn on quietly is pulling out the phase inverter tube. The outputs are all matched and bias up with two green lights. Has anyone even seen an SVT-CL do this sort of thing?
Thanks for your help.
