I left a Mark III at a repair shop long ago after being told it would cost several hundred $$ to repair...with my new interest in Dynas I picked it up and found that he had done some mods and had it up and running....this photo shows his mod to the recifier tube which looks resourceful but not sure if it's OK or approved by the community here...has he simply added diodes to replace the rectifier tube here? Any analysis or advice appreciated...thx. IA
