AC from amplifier transformer, about 30-40vac
apex ax20
sir,if i use 63v dc of this amps...then out put will be 250w rms ..then how much is the bias current per pair output transistors??
please picture here

AX20 use +/-60V rail voltage, I won't share pcb designs in future.

I was making a different layout this time I add the option for TO-3 and also regular transistors example (MJL3281A) can be use too I just wan to show you guys that with some patience this can be done I think looks pretty good 🙂

hy,
i have a request on you about this amp.
i made it but with a two pairs with final tranzistors and +/- 75 v power.this is the transformer who i have it.the problem is bias who can not change the value.is fix 9ma.can you help me with a answer about this?
thank in advance.

Mr Juan very nice job i'm waiting with a lot of patience for the TO-264 version if you want to share the files. AX 14 is a very good amp and adding the Protection on Board it's a very good idea .
sorry but my post is not in the place i waana be.is about this amp APEX AX14.

anybody have the ideea why this amp can not change the bias value and have a lot of distorsion?
my power source have +/-75v.i put two pairs final tranzistors for each chanel.
i wait for solution.
thanks
