Update:
Neither the aerial connections or the AM/FM tuners would affect the amplifier operation since the aerials are not electrically coupled and in any case, the tuners are disconnected from the preamp and main amplifiers when selecting a different input source. There is a block diagram on...
Hadn't turned this one On in a couple of months. Picked it up again, fixed the broken antenna connector...connected an AM loop antenna... worked for 15min and it turned itself off.
The male connector already had the central prong broken when I found this unit in the trash. Today I removed the...
Very interesting, thank you very much for your time so far.
If the guitar expects a load of few megaohms from the amp for maximum power transfer and if the capacitors need replacement, should I get rid of that input stage and add a buffer of some sort?
Something like:
Q1 - J201, MPF102...
Thank you for you help. If I understood correctly:
W1 and C2 form a low-pass filter, cutting all frequencies above the critical frequency defined by their values. W1=10k and C2=100pF; F=160Hz
C1 and R1 form a high-pass filter, cutting all frequencies bellow the critical frequency defined by...
Bought this little amp from ebay and it works great amplifying my portable mp3 player.
**broken link removed**
It's a variation of the circuit featured in the datasheet, as it includes C1, C2 and R1.

1) What is the purpose of C1, C2 and...
