Philco Canada 35A or 41-712 Tropic
#22

Even manually shorting out the junction of caps (40) and (41) (on the 41-712 schematic) had no effect on tone, so I'm thinking either (40) or (41) is open. But I decided against going any further - the radio plays very well as is, so I put it all back together and placed it back on the shelf with its Tropic brethren.

You guessed it - I did not have the end of (40) that goes to the plate of the 7B5E output tube connected correctly. DUH! Icon_crazy

Once that end of (40) was soldered to the plate of the 7B5E, the tone control began working correctly.

So now the 35A is back together again, back on the shelving unit in my home office again, and is totally complete. Icon_thumbup

I knew you wouldn't leave it on the shelf in that condition Icon_wink

Glad you got it taken care of.... I've enjoyed your work on the Tropics, a set I was previously unfamiliar with, thanks!

Thanks for the information MrFixr55.   It's tube amplification and not solid state. TOMfklown — 11:27 AM
