I guess i this here, the 7H choke george sells and a choke you wuold find in a JCM 800 2204 the same. Do they perform the same task i should say. I have run away volume and red plating (melting if I dont turn it off ) problems.

where might I begin for run away juice ( volume increasing, red plating increasing hum increasing ) problem... thanx
