Can Someone advise if using an E80CC in a Mcintosh Mc-225 PI section V2 & V4 12AU7 position will work safely in the circuit.
I rolled a pair of E80CC's in place of the 12AU7's and they do make a difference. I like the sound but the higher heater current has me concerned if the the circuit will handle the higher current safely over time. The E80CC is recommended for PI circuits that use the !2AU7, but some place it in the driver and cathode sections with varied results.
I placed a post in the Mcintosh thread just asking if anyone tried this move and no bites.
