I bought this Phillips 212 new from HI Fi Buys in 1972. One day it would not turn on so I started looking around on Ebay for parts. Found a place selling on off switches for $12.00 so I ordered one. Replaced the on off switch and noticed when I turn it on it kicks the breaker on my plug in strip. Well, I wonder what is next. Probably the motor. I have a parts 212 I saw one day for $25. Anybody ever messed around with one of these?

I just repaired an 877 last night, so Philips is still fresh in my mind, LOL!

You may have hooked the switch up so it shorts the line :hot:

The motors in those, even if shorted, couldn't do more than pop TS440, a BC338 (use a 2N2222 if it is popped).

Transformers rarely short, but test the primary with an ohm meter (snip & strip the wires to rule out primary side bollox). Should be >2 ohms for that little guy and likely between 4 and 5.

After that's done and before re-attaching the transformer leads, put the ohm meter to the plug and turn it on. Resistance drop to zero? Yep, switch in wrong or a bum switch got sent.

As for the rest of the table, recap the 'lytics. Most TT's I do come alive after that :D
