I'm planning a Princeton Reverb build and since all of my cabs are 16Ω I'm looking at this multi-tap output transformer, which the manufacturer confirmed is the best match for a BF Princeton Reverb. Thing is, the classic Fender/standard 8Ω Princeton Reverb output transformer reflects an 8.5kΩ primary impedance, while this one's primary with all 3 4/8/16Ω secondaries is 6.6kΩ. My question, not having a ton of electronics knowledge (but more each day thanks to forums like this): What's the impact on the amp circuit to have a differing primary impedance than it was designed for? I understand I can double or halve the primary impedance by using speaker mismatches, but the starting difference isn't large enough to make this useful. Is there something in the circuit that needs to be done to compensate for a nonstandard output transformer primary impedance? Different resistors? Bias adjustment? My main concern is that none of the components will be damaged/overly stressed in the long term, but I'm also interested if there's a widely accepted impact on the tone, since I definitely want this amp to sound how a Princeton Reverb's supposed to sound.
