Small Pignose Amp Schematic?
« on: April 22, 2004, 06:43:37 AM »

Howdy All,
    I was given a junk Pignose, the little portable, with the "pignose" on the front model 7-100-(R)  It has roughly a 5" speaker.

    One of the two transformers on the circuit board was not soldered onto the board, and I do not know which way to orientate it.  It is the larger transformer.  (both sides of this transformer has 3 taps)
     Anyone have a schematic or knows which way the transformer goes into the board?  The larger transformer also has a red stripe on the top on one side of it, if that helps.
     Also I just measured each side(ohms)  The red stripe side has 1.9 ohms outer tap to outer tap, the other side is 5.1 ohms outer tap to outer tap.

Thanks!
Arn C.

I don't have it on me at the moment, but I believe it was posted around since I know I snagged it somewhere on-line.

Is there a chance that I could get that schematic, too?  I have some transformers for that type of amp that need a good home.

Thanks in advance!

While checking the Pignose schematic Marcos sent me, I remembered this excellent one.

http://www.redcircuits.com/Page52.htm

I wanted to make a pcb layout for it, but ... it's still not done.I would be curious to compare it to the sound of a Pignose. I like discrete  :lol:

I need help with a vintage pignose 7-100 r. I have worked with it enough to get sound out of it. When I received it the batteries has destroyed the majority of the existing wiring for the input & power switch/vol knob. The battery pack has been removed and would love to just leave it as a plug in amp as I do not care about the battery power nor do I want to corrode the repaired solder joints. I have photos i can supply.. I have the schematic as well, although, it confuses me, I have done guitar restores in the past

Red wire i believe was originally the battery positve.

Blue wire shows as a ground by way of volt meter.

Black wire shows as a ground by way of volt meter. Which i believe to be oringally battery ground..

This is my power switch/input side as i recieved it..
http://s92.photobucket.com/user/evon_ishot/media/WP_20140626_006.jpg.html


Where do these wires go!? If I use black to the top of input that is empty but has old solder on it in photo and twist the blue and red together I get sound.. although it is very low and very fuzzy.. Huh
