HELP: High impedance load for SET amplifier

Posted by OperFan (A) on August 6, 2020 at 01:17:03

Hello there to all SET audiophile fellows,

I would appreciate any hint/help concerning the following use case:

I own a commercial SET amplifier (Coincident Frankenstein Mk3); it has 8 and 16 Ohm speaker taps. I would like to experiment with a field-coil speaker/chassis that exhibits an impedance range of 24-30 Ohm.

Generally speaking, I know that with SET amplifiers "higher" is better than "lower" when it comes to speaker impedance...but there might be also more subtle aspects.

So, my question:
Could I encounter issues concernign power transmission, tube life span or dammage risk for the output transformer ?

Thanks in advance!
Best regards,
Adrian
