Greetings.
I have a RAPAR TPA-50 P.A.
The STK032 amplifier module has died,
and seems to be N.L.A.
The output of the amp module goes direct
to the 8 ohm output terminal.
The output also goes to a transformer to supply
the 4ohm, 16ohm 70v and 100v terminals.
I tried using a LM1875T (S.C. Dec. '93) to replace
the STK032. But I don't like the smoke coming from
one of the resistors or the sound from an 8ohm speaker.
The power supply is 50v (not + -).
The output power rating of the P.A. is 25W.
Can anybody suggest what I can replace the STK032 with?
Thanks,
Russell Griffiths.
