This is my first renovation, and my first post, so I'm a bit reticent in case I have my finding wrong. But I don't think so!
This is the Marocni 207, electrically identical, I believe, to the 206, and I'm looking at R18 / R19 in parallel, which feed voltage to the screen grids of the first & second stages of the RF path. The components list shows these as 2K6, 2W each, to give a combined value of 1K3 at 4W.
In my restoration of serial no. 4511, the parallel pair shows 40K instead of the advertised 1K3. That's a clue! But the resistors themselves have colour coding for 26K, not 2K6. Looking at the specs for these two valves (sorry, I can't get used to calling them "tubes," even though I now live in Canada), it's clear that a value of 1K3 for the resistor pair just doesn't work. 13K is better.
So I'm postulagting that the components list has the values wrong. Does that make sense? If I get agreement, I'll re-post this as information.
I'm finding that antique radio restoration is a combination of detective work, logic, and hard-earned knowledge. I love it!
