1960 Westinghouse H60ACS1 Stereo

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?

[electra225]

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?

[Hi-Fi-Mogul]

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 !

I always thought the spec for the EV-26 was 5 grams, but this original ad from 1958 says 6 grams --

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.

[electra225]

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.

[William]

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

Bill

[Hi-Fi-Mogul]

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.

[William]

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.

Bill

[Hi-Fi-Mogul]

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.

[William]

It's nice what something works out for the better. Congrats!
