I've been feeding the Wood a steady diet of Jazz and 100,000 ohms was sounding good.Tonight, with about 40 hours on, finally, I played the Saint-Saens 3rd Symphony. Loud. With both amps, the 45 and a yet-to-be-named 50 watt 6SN7/KT-88 P-P. Not both at the same tyme, of course
Horrible! Que Barbarida! Veiled,confused and congested. $29 Radio Shack mics weren't used by RCA so I suspected something wrong.
That, after visiting with Steve Brown today and we agreed how good the higher impedance was.
Switched back to 50,000 ohms and Et Viola, verrr nice. And that's where it will stay.
