need to know if anyone here can draw a schematic for the nady trm6.

ok i will work some more on the tinycad schematic. i can also post it here if anyone would like to tweak it.

does tinycad have a socket symbol, only saw a triode and a pentode.

i could not find a tiny cad image of a 12ax7 socket so printed it out drew the connections labeled everything and also printed my schematic i tried to label the socket by color code.

 

[flashlamp]

it's pin 2 i cant tell if it's correct on the 12ax7 socket the rest of the wires just go tothe 7pin xlr that dont go to the socket. also please excuse my messy hand writing.

heres a jpeg of with the schematic with tube socket , also the 12ax7 pinout based on where the wires were going to the 12ax7 socket..

 

[flashlamp]

heres with full color code, Im wondering if the white wire is really the center tap or there are several connections that i will need to test with my digital multimeter

You might want to re-check your schematic.

Are you 10000% sure you counted the tube socket pins the right way? I'm thinking the datasheet should mention if the pinout is viewed from the top of the tube or the bottom.

What would be the point of one side of one of the transformers being 1) shorted out, and 2) also having a resistor in parallel with the shorted connection?

And where do the 7 wires from the xlr connect to?

Are there any schematics of other tube ribbons around that could give some direction to help get in the same ballpark when trying to draw this out?

I do not know does could the goldenage tube ribbon have a schematic?

 

[scott2000]

Only Golden Age mic I see a drawing for is their condenser TC-1

It does have the 7pin power supply and a 12ax7 though unrelated to your mic....Maybe you can get some direction from that anyway...
... Wouldn't be the worst idea to see what voltages are going where from the power pins. You could even start to make sure heater voltages are getting to the tube for example.......

Keep at it....

I sent my first drawing to PRR to try to decipher..

He was actually quite easy on me... it was, I think he called a puzzle he couldn't understand....lol

Really miss the times when PRR was around...

I'm not too nostalgic, but thats a good reason to say, "Back in the Day (when PRR was around) it was better"
