Repro knobs for Motorola VT71, VT73 available now

I now have knobs available in the dark maroon color for the Motorola sets. I'm making plain, plain with an indicator dot, outer tuning, and inner tuning knobs.

I'm not sure which control uses the dot and which doesn't. I don't have one of those sets. Would the dot knob be used for Volume, Tone, Contrast?

Also available again are the CRT masks.

Great news

Funny, I have several of these sets and never noticed that indicator dot before
I'm sure it's for the combination power switch/volume knob on the left as you face the set.

I have seen some sets that do not have a center "fine tune" on the channel selector. A knob with a dot would work fine for the channel selector of these sets.

The volume/contrast knobs have knurled shafts. The channel selector on sets with fine tuning is sorta rectangular with a metal reinforcing collar.

Do the sets without fine tuning use a knurled shaft for the channel selector?
I've never seen one - only read about them. I think they're the earlier chassis runs

Yes, the shaft is exactly the same as the volume and contrast shafts.

PS my channel knob is missing the dot, but somebody scratched a line on it with a file to indicate the channel selection

Ugh I hate when people deface knobs.
Do you happen to know what chassis run your set has (TS-4??)

Seems like it was a "B or C"... gotta dig it out and look...it is at the *bottom* of a stack of 5 electrostatic sets, behind some other stuff.

No need to dig it out on my account - I was just curious.

I've a few of those rascals here. I know the J version has the fine tuning. Great news on the replacement knobs!
