Garrard 4HF Pitch control
Hi I have a Garrard 4HF deck but unfortunately the pitch control (I think that's what its called) isn't working the 4 speeds work fine but I can't fine adjust the speed. The small knob turns but nothing happens. Any help please. Gary

I think they were quite stiff so maybe the knob is loose.

All seems tight.. The knob turns and theirs weird kind of spring noise at the extreme limit of the turn in both directions??

It's a wirewound control so it would seem the wire has probably broken. Need to take it apart to find out. Probably a standard value pot can be fitted in it's place.

"The Classic Turntable Company" may have spares.

I dont think a standard pot will work, if I remember, the pot is around 20W, maybe more.

Hello. This was discussed on Vinyl Engine and a wiring diagram posted that might be of help. The high voltage diagram is the one for UK mains.
As Michael says, it will need to be a high wattage control but not sure of the actual rating. Hope this is of some help. Edit: further reading shows a 25 watt OHMITE RHS10KE being a good fit if you can find one. David. |

The pots are available on ebay but not cheap. About £30 inc post.
See images. David. |

As a sort-of aside, I was amazed to find (while looking for something else) that RS sell 'rheostats', including the one in this thread :
https://uk.rs-online.com/web/p/rheostats/8915379/ Some of the higher power ones are _very_ expensive, and I wonder what they are used for these days. |
Re: Garrard 4HF Pitch control
The control for a Garrard RC98 would probably work. But this isn't much help because if anything, the RC98 is uncommon; fewer were made than the 4HF.

Hi Skaman. Any news on this? I am interested to hear if you got it sorted as I have a couple 4HF's and the pitch control is a weak spot on these. The actual fitted controls are the sort you would find on the back of TV's.
I had my first 4HF back around 1972 and the control smoked and got replaced by a couple of wirewound resistors (by my Dad). We later discovered that the motor had shorting turns. On my later 4HF's there is a slight burning smell if you adjust the control but it clears and the motors only get warm so I assume Garrard only meant the controls to be adjusted sparingly. David. |
