Garrard 4Hf

OK, l'll try an ascii drawing...

The 3k and the 6k resistors are the ones someone added to replace the pot. The 10k and 750 ohm are the original barrel shaped resistors Garrard mounted on a single bolt below where the pot used to be. I am guessing the Black wire that has come loose (the x on the drawing), probably came from the junction on the 3k and 6k resistors (simulating the wiper of the pot when it's set to about 1/3.)

Code: Select all

Nice post.
Will try this at some point. It may turn out to be less of a headache than trying to build a new pitch control.

Almost forgot; for the Shure M44-7 cartridge the ideal counter balance I found is 5 grams when located at the very back of the arm on the vertical side under the stylish 60 degree angle.

Yep, that was where it came from. All OK now. Although I am looking around for a 10k power pot to restore the adjustability.

What a fantastic forum...!
Thanks vinylengine people...!

So did anyone ever upload the circuit diagram?

[Damien Taylor]

My copy of the service sheets never had a schematic included, maybe there never was one available. Values for some items are noted in the parts list.

Found these wiring diagrams in the service manual. I'll upload the whole thing when my scanner stops being a piece of junk.

Just downloaded a copy of the Garrard 4HF service manual, I've been looking for this manualfor a while. Thanks Vinyl Engine people and to the uploader.
