can anybody figure out what this circuit is?

hi guys....this is in the "fal treble booster" i got on evilbay..

i don't think it's original, tho the pcb appears to have been factory mounted to the casing with the same crap they used on the battery holder, some double sticky sided foam kinda stuff.

that said, the battery is for a "um5 or n size" battery.

there's TWO transistors, both c1923 y g5's... i looked 'em up, they may be 2sc1923...

the board is marked with the number 4030 on the trace side...

there is a small inductor

both elecros are 10mf@16v

there's 6 resistors, 12k, 10k, 100r, 33k x 2, and 180r

i can't make out all the discs, the first one is 100p, 10n, the rest are marked with 3 or 4 ...pf? there are 4 ceramics all together.

as best as i can see (which isn't well unfortunately, the parts are labeled like this


r1 10k
r2 12k
c1 10u
c2 100p
r4 100r
c3 10p
r 5 180r
r6 33k
c4 3p
c5 10n
c6  4p
c7 10u
the "transformer" says 28-4030

here's some pics

i tried to outline the traces a little, and labeled the underside with ins and outs













so...what do ya think?

i'm gonna splice it back together and try and get some signal thru it...thanks guys
