I've looked back through my posts but can't find who sent me link to buy this amp board, so I have it , came w/o any instructions and two of the connections are only marked in Chinese. Any help on how to use this as a CBG amp would be appreciated!
here is where it came from> http://www.ebay.com/itm/131832286247?_trksid=p2057872.m2749.l2649&a...

interesting find there David. certainly has potential. if i can decipher the chinglish i think this can run from 9 v or 12 v. seems to have a volume out and reverb controls and 2 x 1/4"inputs. if you can afford it it is worth a try at $10...closer to $15 AUD for me.
a little research on the PT2399 delay/echo chip gives good reviews ...
are you talking about combining the 2 outputs of the preamp board to feed into a mono power amp section? 100k pot with channel 1 on one outside leg and the other channel going to the other outside leg and take the output to the amp from the centre wiper leg through a 47K resistor.
if you use the karaok reverb board from ebay you listed i dont think you need to. from what i can figure out from googling it and reading the amazon listing, the first two pots are mic1 and mic2 volume pots and the third is the delay/reverb control. so you get mixing of two signals at the preamp.
Thanks for this.
very nice! i cant seem to get wooden boxes in Brisbane, well not at a reasonable price.
Very nice, what type of amplifier did you use?
