Wax comming out of the TC366 run capacitor

[srinath]

I opened up my TC366 which loses speed when near the end of the tape. So I thought yea run capacitor.
So I pulled the back off.
Then the run cap was easy to spot. It was the cap connected to the motor.
OK so it has a plastic cap on top.
That cap seems to have melted wax in it. Worse yet was there was a candle like drip and cool collection of wax on the back panel - presumably it was used lying down a lot.
So now what is filled with wax ? was the plastic cover for the capacitor filled wth wax ?
Is the capacitor itself filled with wax ?
Now The capaciter looked fine ? I guess it can still be low on capacitance.
It was a 1.5uf 250 wv cap, and rather big. Can I substitute a modern electrolytic for it, which may be very small ?
Can I exceed the capacity ?
And can I exceed voltage ?

Thanks.
Srinath.

That cap is listed as 1.5uF + 0.5uF 250V cap, and it looks like it's connected on the AC side of the power supply. Probably a motor run or start cap. You may have a difficult time finding a dual cap like the original one, but you can probably find two separate ones to do the same job.

Someone will chime-in as to which type of cap it is (run or start), then you can go from there.

Wow! Luckily someone has one on the large auction site right now (#260980144638), so there you go. It looks like the 0.5uF is for 50Hz operation.

Here is a link to Ralph's page all about the TC-366. If you scroll down you'll see the small replacement he is using in this restored unit. I have a 377 and the run cap is still good for now. http://www.angelfire.com/electronic2/vintagetx/SONY.html

Vfr800iman: Its not a double cap, its got 3 wires, 2 black and 1 white that go to 2 posts, the 2 black to 1 post and the white to the other.
Thanks shaner2r I'll check it out.

1.5uF VAC cap

For these sony models the run cap 1.5 uF is for 110v 60Hz and 2uF is for 220v 50Hz. You can replace it with this for instance.

Thanks, I got it. Now I have heard we can use a cap meant for a fan from home depot, is this the same thing ? Just curious.
Thanks.

It is a double cap, it's just they're both in the same package

I just replaced my motor run/start cap for my TC-366 this week.
My deck had the three symptoms of a bad cap..
(1) no torque, (2) motor runs hot, (3) wrong speed.
I got the cap from Bob @ http://www.vintage-electronics.cc/vparts.html.
It was a newer style cap as shown above(in post #6). Bob had also provided a nice instruction sheet.
This solved all my motor issues. Runs great now.
good luck

Works great after cap swap.
Cool.
