That's true Mr. Mile and real diyers will never give up till finishing line...

This H class design can be use for high power amps, something like this:

If you want +/-60V, and +/-120V you need 5 pairs of outputs and 5 pairs mosfets like IRFP240/9240.
Nice Willy very nice. hey my man I'm putting together your version of AX-11 MKII and well if some one can help me out I will really appreciated, 😀 today I'm putting together must of the component I have on hand I just need to get me the transistor MPSA-92,BD679A,MJ15003/4,MJE15030/1, and resistors 4R7/1W and the emitter resistors 0.22/5W, so far is going well 🙂, here my question I do not have 331 caps, can I use 220pF or 180pF instead ?

Mr Mile, for HX 11
I have 2 transformers 25V-0-25V AC (~35V-0-35V DC) and
a 45V-0-45V AC (~63V-0-63V)
What transformers Voltages and VA do you recommend for Maximum.
Thanks

Wow... nice progress my dear Juan very nice... just one question i saw that yellow cap standing up high in front of MJE340 notification says 220p/250VAC... about 331 cap i suggest to go for 471 to compensate but let Mr. Mile to confirm what is the right replacement value.
Regards,
thanks buddy! 😀 well I guess we should wait for him I really don't want to mess it up, it took me a long time to put it together today 😀 ,the yellow caps is just placed there as reference, not sure if I can use it or not just to see how it looks just that, I do not have many components but also I do not want to change a really important components with the wrong value and damge the circuit.

Hello guys!
Yesterday I decide to use 180pF mica looks really good 😀 I'm going to order the transistors I need and some resistors that I don't have also the insulator for the TO-3 I don't have those, so yes I need them, the board on this pictures look a bit large than what it is but is ok on the second one I might just leave in that size it does not bother me at all well here are the last images then I have to wait for the part the get here in Puerto Rico good day guys 😀
