2300 ohm vs 5000 ohm output trans question

Hi all,

WHats your take on using a 5000 ohm output transformer for quad kt88's?

I have a few amps now, and I think they use 2300 ohm output transformers.

Am I facing a power cut ( half the power than a lower rated trans) or I am getting an opportunity to use more output tubes (if I can use 4 on a 2300 does than mean I can use 8 on a 5000 ohm one)

I'm looking at using 120 watt power trans with 160 watt output trans using at least a quad of kt-88's (unless 5000 ohm trans are a 6l6/5881 item, then I can use those as well).

I'm thinking of a mono block architecture with individual power trans per channel.

thanks your your opinions and comments.
 
Hi Speakerfritz,

By using a 5000k output transformer you will have a power cut.
You will have about 30 watts/8ohm with quad kt88's in triode with the 2300 ohm output transformer.
With the 5k transformer you will end up with 13,8 watts/8ohm; output resistance (damping factor) and distortion will be lower though.
