Don't worry, I harass about it regularly. In mean time, consider PoP. Basically same amp, but with regular mosfets. Same spooky sound. XA 252 still all time favorite!A little too quiet here, did I miss the placing the order scrum?

New builders out there of the XA252?
This amp deserves more attention!
Mine is playing between 20 and 40 hours a week. I push it to clipping sometimes, still zero issues so far.

for all previous gens of pcb, problem solver is additional resistor in parallel to optodiode and changing BD follower pair to pair of more sturdy ones
one of the Boyz already did it (just starting morning coffee, bare with me) but I can't remember which type
I bought quantity of TTA004B/TTC004B for all future kits
Agree with you Bensen! Fantastic amp, no issues here.🎶🎶🎶
The only problem is the season has changed and the big Class A’s have to go into hibernation till the Fall.😟

that's no brainer
in Summer use small A Class amp
in Winter use big A Class amp

That was me
I guessed ....... but better wait for that coffee to kick in
not that I'm more clever after the coffee, just less sleepy

Yes it does! I want another badly, and will order as soon as available. ZM already said, it's a time thing, once some it available! Mine is in "repair shop" as I build a new board for itNew builders out there of the XA252?

In mean time, PoP is very similar, basically same amount with "standard" mosfets. With easier to drive speakers, not much difference. With more difficult loads, still spooky sounding, not as spooky as with XA25.

also not brainer - if you use BIIIIIIIIG speakers, you can use small A Class amp entire year

I must confess I stopped the project some time ago, but my devil inside wants to have this amp, period 😈
So I'm in consultation with Mightiness and will try to recover my old boards, because - mea culpa, mea maxima culpa - I cannibalized them for other projects 🙈 and I also moved some smd parts during desoldering... hope I can repair it.
But I definitely back on board

Probably not on the ZM BIIIIIIIIG speaker list, But my Klipsch Forte's are as big as I could go without being skinned alive!! 😆
As it is, I have aluminum silver and black boxes all over the home
Besides, what fun is it only having ONE amplifier??

What generation of Klipsch Forte do you have? Yes, amplifiers are a bit easier to swap out than big speakers. I enjoy having a variety of them 🙂
Vunce, Which amplifier is the substitute for xa252 during summers?The only problem is the season has changed and the big Class A’s have to go into hibernation till the Fall.😟
Guess I will have to drag A7 speaks up from basement.also not brainer - if you use BIIIIIIIIG speakers, you can use small A Class amp entire year
