Elekit TU-875 12AU7 Preamp

Mr. Fujita is back to his office today and here is his reply regarding TU-875 power by DC (battery) instead of switch adaptor:

"There is no problem to operate TU-875 with battery. However voltage of TU-875 is 7V
and it is not appropriate for smooth operation for it.
If you replace R83 (0.47ohm) to jumper wire, you could operate it with 6V battery.
Approx 2 ampere constant current flows when you use 6V battery.
So please be aware of the capacity of the battery when you use it."
