7581As in the Fifty/ Fifty?

Post by joey_truelove » Tue May 29, 2018 7:55 pm

I do love the basic sound and operation of the Fifty/ Fifty I have. I just wish it had some more headroom. Do you think the TS 7581A would work in my favour here? Could the amp even handle those, you think? The PT looks rather sturdy, I think.

If not then I suppose I'll just have to fit a heavier OT and run the amp as one 80-100W:er.

Yes, you should be able to run those. You'll get more clean headroom out of them. They CAN be used to increase power output but that requires changes to the plate voltage and drive parameters.
