Official Blackstaramps Forum

I am a retired Fender Amp Designer - 18+ Years - Last 12 designing exclusively on the EVH 5150III Series. Now working part time to keep busy doing amp repairs and mods preferably for tube designs. Had a Blackstar HT Club 50 MKII come in with and occasional tube runaway issue. Cannot find any support schematics online to help dig into the problem. Any ideas where to get schematics?
