These look really great. Sadly the whole whole eBay bidding situation pushes them out of my price range. Maybe if I can sell my current amps. It never ends.
This is probably the best single ended pentode version that he makes, and going $1550 delivered (no bidding). $1550 for a hand built, point to point wired tube amp from someone like Had is a pretty good deal, IMO:https://www.ebay.com/itm/153649693112
On the other hand, the budget is the budget and if it's out of the budget price range, that's just how it goes...Edit to add:
Part of the reason I like his design so much is that it only requires 2 output pentode tubes. My prior pentode tube amps all required 4 output tubes. The nice thing about the Inspire amp is that I can definitely afford some really nice NOS tubes in pairs, but definitely NOT afford those same NOS tubes as matched quads.
Add to that the fact that you can roll a ton of different pentodes, that makes it close to the bargain of the century, IMO. For example, tubes I have already rolled in my amp include: EL84, 6F6, 807, 6BG6-GA, 6CA7, 6K6, 6V6, 6L6, 6L6GC, EL34, KT66, KT77, KT88, 6550, KT150, and a couple others that escape me at the moment.
