[QUOTE="Mars, post: 457981, member: 817"] I have actually already done the modifications, and the amplifier is playing music. I removed the EF86's and the mic xlr inputs. The OPT was removed and two Mars 10k:8 ohm OPT's were fitted. I also removed the electrolyic caps and old rectifier bridges. Kept the fixed bias setup and the two ECC40 tubes. Each tube was wired like the original phase splitter. Kept the 0.068 mustard coupling caps. I am running the amplifier as a power amp driven by a CCDA 6SN7 preamp. [/QUOTE]
