That looks great, Mr. Mogul, and if you ever travel to Michigan, I have a few Collars that need service too.

That's a great looking cabinet. But 6 GRAMS TRACKING? YIKES!!! What cartridge does this have in case I missed it?
Does it have to be that heavy to trip the changer?

Not to be critical, but I thought an EV 26 would track at four grams or thereabouts. Is there a reason you need to set it for six grams?
A good leader is someone who can tell you where to go, and make you look forward to the trip.

V of Music says 5 grams tracking, and for the trip to work
well, this is a good compromise.
It originally had an Astatic 13T stereo power point in it,
tracking at 7 g.
The tonearm was at 13 grams before I shortened the
counter spring !

Magnavox had a sticker in the changer compartment on many of their stereos that advertised "1/10 of an ounce diamond needle". That would make it 4 grams nominally.....

That was for slightly newer sets that used the E-V 132 cartridge.

You, sir, are absolutely right! The only stickers I have that advertise 1/10 of an ounce are the Stereo Theater and the 1963 Contemporary, both of which use the EV 132 cartridge. I would have sworn the Symphony had that sticker, but it doesn't. I learned something today.

4/5 caps done inside the chassis.
The old 0.047mF B- to chassis cap was
underneath that group of AC wiring.
I found an easier location to put in a safety
cap for that B- to chassis cap.
It will be a 0.01 mF X1Y2.
Then on to cutting off the paper covered E-lytic
can, and drilling holes through the end of
the can stub for the new e-lytics' leads to
go through.
I will also mount a terminal strip for the replacement
1N4007 rectifier to go on.
Plenty of room now that the selenium rectifier is gone.

Looking good, Mr. Mogul, and you have the same soldering station I do.

I got the e-lytic can restuffed, and had to be creative
with the connecting of the neg polarity leads.
I hooked up the Collaro and a couple of little speakers,
for a test.
Even with that separate filament transformer, there was
significant hum.
As with other non power tranformer units, I placed a
10 mF e-lytic cap in the B- to chassis position.
That cut the hum way down to acceptable.
Voltages are in the upper end of range, but OK.
The Collaro tonearm wiring was pretty darn thick,
and still a bit stiff even after multiple cleanings.
It caused the tonearm to skip backwards about 2/3 of
the way through and album.
I removed the old wires, and am soldering in a new set.

Looks good, Mr. Mogul. I have never heard of stiff wires going to the tone arm causing that kind of a problem. Now I wonder if that might me the reason my Berkshire Collaro kind of gets stuck at the end of the record, so it won't go into the reject cycle.

The new tonearm wires did the trick, no more skipping.
These 6CU5 tubes have plenty of power from my testing
with some speakers.
They're rated a bit over 2 watts output in SE circuit.
Waiting on the owner to replace the broken plinth in the
cabinet, and then wrap this up.
