Clear Schematic for 41-255
#16

RossH -

Were you looking at our copy of the 1941 Yearbook, or one that you found elsewhere?

What's really funny is I looked at the pages and saw 255 and it took me 30 sec of looking at the schematic trying to figure out why it wasn't matching what I had before it dawned on me - I had transposed the numbers in my head.

This is perfect. Besides starting to work on one of these I am going to recreate this schematic from scratch. I've done a few ten others but this will be my first Philco recreation. I'll post when it's completed and gone over a few times. 

Thank you very much for your time and consideration in doing this, and a big thank you to all who chimed in.

When you unsolder what has been soldered before the unsoldering, the unsoldering of the soldered is what will be.

Hi Ross,
I don't know if you still need a clear schematic for the 41-255 but here is one that I cleaned up. I added pin numbers on the tubes and corrected 2 part #s (#29 and 33 were reversed on the schematic). Also, voltages are in dark red, and where provided, I color-coded the wire color name.

AH Just noticed 1 error on my cleaned-up schematic...
Part # 27 - the 8uf electrolytic cap...The lead that is marked RED should read GRN (green). Old eyes are not what they used to be!

Thank you, Fran. I'll add it to the mix.
