In most cases it didn’t seem to make a whole lot of difference. Oddly enough it doesn’t seem to affect anything and honestly I think the reverb is better now, but that function is never used.
May Thu 26, 6: Looks 2m2925 perhaps I could use a 2N Made a mistake for the transistor number.

So it looks like I may only need one transistor on the post amp board which is the 2N as the other two on that board form a turn on delay that mutes the audio while the rest of the organ comes up. How much difference would that make if Datzsheet just replaced all the 2N with the 2N? Should be 2NA not 2NA The background noise is almost gone after replacing the 2N transistors on the reverb board. Books Support This Site: 22925 looked and I can bypass the reverb board far as the audio signal is concerned.
PDF 2N data http: Previous topic Next topic. Could the 1 volt increase just be what dattasheet normal signal level was when the organ was new? If I wanted to do away with the reverb board completely how could I derive the 28Vdc? I used to work on organs quite a bit, years ago.
Transistor substitutes 2N sub found Posted: This is a Conn model organ. Users browsing this forum: Anything related to the above. I’ll post the picture of the schematic in the main restoration topic viewtopic. Jan Tue 05, 2: Also if I still have some noise I will have to replace the 2N transistors in the solo and accomp mixing preamps and the complex voice preamp.
I can check it as the output of the reverb amp that drives the reverb tank has a measurement point where a DB reading is listed. Given these transistors just amplify the audio signal I am thinking any suitable sub will work ok.
Mouser don’t know when they will get the MPS back in stock, but a NTE is a suitable sub and since this is just used to regulate the rod bias I feel comfortable in 2n292 that one. Transistor substitutes update Posted: Dec Mon 31, 3: I will need to datashet a test to see if the gain is unity or very close to unity as the reverb board sends the signal through one transistor and takes t he signal from the emitter and applies it to the emitter of the last transistor on the board to allow the clean signal to pass through.
Makes it harder to find out why the 16′ bass isn’t working as I was hoping it was a 2n29225 transistor. Jan Tue 05, 4: May Mon 09, 4: Watch out for the fact that those have different pinouts!

The only issue I saw when testing the board at work was that there was a 1 volt increase in signal voltage out of the second 2N stage right after the input stage when I used the 2NA transistor. Transistor datasyeet 2N sub found. Which section do you need to see? Still have a little noise that changes with the expression pedal setting which is after the post amp board so I will replace the three transistors on datxsheet for good measure.

Page 3 of 3. It is the 2NA and I happened to find some in my stash. Baldwin liked to use those 2Ns, mostly “green” but occasionally “orange” as well. What I wonder is this. Can you scan that section to share? After a datwsheet while I decided to tackle the noise issue.
I found a suitable sub for the 2N What brand of organ is this?
