hi apex,
i tried your darlington topology.and guess what everything was ok no abnormal
readings.no sagging of voltages. dc offset of 2mv.same reading on every collector.
then i switched back to normal driver stage with mje15032/33 .switched on
2.1mv dc offset.no voltage sagging everything normal.then i saw i forget to add
22ohm resistor which was connected to both emmiters of mje15032/33.as i
connect then every thing messes up.30 mv dc offset.voltages sags 60 to 38
and-60 to-14.different reading on every collector.what should i do.
thanks

Use darlington topology if work good on your amp.

i have 2X18VAC 50va..on 1000uf/35v i have 22vdc..
thank u sir....
Use 2x20vac, and you must have 28V DC on 1000uF/35V.

Hello mile's can you share an idea what changes to be done when triple ef to be use likewise proper adjustment of bias
It's OK, bias must be readjust.

Thanx to Miles
nice project

hi apex,
cant use tripple darlington as pcb dont allow this.i have to wire them seperaterl
cant i raise the value of resistor say 82/100 ohm or add a 100nf across
the resistor .raising the resistor value 100 ohms makes thing normal.
i want to complete it as soon as possible
thanks in advance

Nice work, thanks for picture, any coment about sound?

WHICH PSU YOU USE?
WHAT IS YOUR TRANSFORMER DIMENSIONS AND THE PRIMARY WIRE GAUGE, SECONDARY WIRE GAUGE.?
