I am sure that this subject has been addressed but as a newbie and still trying to find my way around so any direction would be welcome.

I have just put a 4" coil on the machine and it has been suggested that it is worth adjusting the GB pot inside to get the best out of the setup. I gather a ferrite core is the simple 'tool' to use to emulate ground.

Two questions, 1/ how big a peice of ferrite? 2/ what exactly are you listening for?

I am assuming that you set to all metal mode.

Many thanks

That was just discussed on another Forum using the ferrite core . I hope I can find the link quickly unless someone else answers before me . I also remember a silver sabre mod page posted somewhere ? You might want to do a google search again "Silver Sabre II mods".

This sounds deep. Is there a reason you do not ground balance it the traditional way?

Peace

Sean

Deep!!Is that a pun Sean?

The Silver Sabre has automatic ground balance circuitry with no adjustments available on the outside, however, there is a pot in the middle of the board that is used to fine tune the curcuit. The argument is that different coils can alter the efficiency of the balance, hence the facility to tweek.

Hi Paul!
I've got a "Laser B2" which is basically the same as the sabre.
You are right about the pot in the middle of the board.
Last time i "fiddled" with it I used a "hot rock" (basically a largish bit of "Coke")
Set the pot to just off silent with the coil close to the "coke".
Not sure if it was strictly the right way to do things..... but it seemed to work!
Whatever you do don't adjust it with a "Jewellers screwdriver" (they Bu**er up the pot too easily) ... get one of the plastic adjusters that Maplin sell.

P.S.

Got your mail! - Will speak soon

ATB

Paul
