PNP Rangemaster Doesn't Have A lot Of Volume/Help Needed

[Wagster]

I just built a PNP Rangemaster.This is my 1st attempt at a Perf build.

I used this layout http://www.aronnelson.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=3096&g2_serialNumber=2

I wired the switch like this diagram http://www.aronnelson.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=11083&g2_serialNumber=2I added a on/on DPDT input cap switch.It sounds like a Rangemaster but with less than half the volume.I can't figure it out on my own so I need your help.

Here are my readings

Battery = 8.94
Voltage at the circuit board end of the red battery lead = 8.94
Voltage at the circuit board end of the black battery lead = 8.94

Q1
C = 8.81
B = 8.21
E = 0.02

I also used a resistor socket so I can bias Q1.I know the collector is a little high.I'm just trying to get it to work 1st.

Thanks,
Billy

From your voltage readings, it looks like it's not biased properly. Log on to GEOFX and read the article on the rangemaster for correctly biasing your germanium...

I'm already aware of that.It's doesn't have a lot of volume.It never reaches unity gain.I 1st intalled a 100k trim pot.I removed that and replaced it with a socket.I though I might have had a bad pot.That didn't change anything.

you might want to check for any shorts there... i think that may be your culprit.

First of all, that's a layout for an NPN rangemaster, not a PNP. If you built it and powered it just like that, it will not work.

You don't say what transistor you have, whether you looked up the pinouts, and the rest of the stuff requested in "what to do when it doesn't work" so I can only guess that you may have built the wrong-polarity version.

Wow I'm such airhead.I just realized I built a NPN version using a PNP transistor   Can I just reverse the 47uf caps to make it a PNP?

[kurtlives]

Also reverse the battery connection and any other polarized component...

Dont worry it happens to the best of us...

[Wagster]

I'm sorry for such a newbie question but how do I reverse the battery connection?Here's the layout

* Edit* Never mind I think I got it 

[Wagster]

Now I'm getting a -2.65 on Q1's collector.Could I have fried the transistor?When I play a note it cuts in and out but it's now a lot louder.

Thanks,

Now it's misbiased, I think.

Post the voltages and other info from "What to do when it doesn't work."

  Start with a correct schematic is the best option at all times.
  But basically all the polarized components must be reversed to make an NPN be PNP or vice versa.
  Polarized capacitors need to never be reverse polarized [ie negative lead must be more negative than positive lead], and diodes...if you have a PS diode in there of course it should conduct if RPolarized, so that'd be another polarized component to pay attention to.
  The transistors B/E marking has an 'arrow' inside the transistor which indicates which way the internal diode is oriented, ITCase of PNP it'd be pointing opposite to NPN...consult the data sheet of the transistor you're using, make the pins [E/B/C] match the correct circuit for the transitor type.
  Polarized capacitors can be used for input/output...pay attention where necessary.

I got it working.I had the switch wired wrong   Great sounding pedal with my AC30.I found that I like it biased lower around 6.1V

Thanks for the help guys.
