The bracket is reversed, and bonded to the chassis with some of the UV cure adhesive I've tried before. a change of tack was required, there just isn't enough strength here. as again there were sheered off screw fittings. Once the epoxy had cured it was flattened off, and it was at this point I realised that the top plate was no longer secured to the chassis.

The speed change detent arm was exceptionally seized up, and required plenty of heat to get it to free up. The Beatles are now back in stereo (which is a pity tbh, the mono mix is far superior.)įeet up, Sunday afternoon listening to The Blossoms. I use a coloured sharpie to mark each one.Īnd finally trim the leads, and solder them to the output connector. Refit the cartridge slide, with three wires diconnected, and, using a multimeter, identify each conductor. Refit the arm, and nip the bearing up just enough to remove any play. My teflon wire is once again employed to pull the wiring through the centre of the gimbal. The bearing support can now be re-attached to the arm tube. Pass the new wiring through the insulator, and refit. Loosen this to remove that white plastic insulating "top hat". This is the angled grub screw I talked about earlier. It easier to make it shorter )Ī piece of teflon wire is used to pull the new new wire through the arm tube. Always allow for much more than you think you'll need. The headshell is then removed, and four lengths of Litz wire prepared. Undo this, and don't lose the washer underneath it. Bingo, the small silver cover pops out, and reveals a small black plastic nut. Get a piece of blu-tak, and stick it over the pivot.

I spent a few minutes looking at this, trying to work out how to get the headshell pivot apart. I didn't do this at this time, and broke the wiring, not that that mattered. There's a small grub screw at an angle, losen this to remove the plastic insulation "top hat" which the wiring passes through. Removal of two screws allow the separation of the arm tube from the bearing support. Slacken the arm bearing off, this will allow extraction of the arm. Undo the gimbal housing screw and slide the gimbal housing down the arm and put that somewhere safe.Īs there was no doubt in my mind that the wiring was at fault, I just cut it off. Ĭartridge Slide out first, and put it to one side, so we don't damage it. Now I'm one of those odd people who actually enjoy arm wiring, but this could be a little daunting.Ī quick google search chucks up loads of people who say it can be done, but it's very difficult neigh on impossible etc etc etc. MM is very quiet, as is everything else.įunny, didn't think I had the mono press of this. The moving-coil input is a touch noisy, but looking at it's topology, not surprising. The amp is a really impressive performer.

The voltage on the emittor of Q617, a 2SB631 is wobbling about as the amp warms up.
GARRARD ZERO 100 HEADSHELL WIRING DIAGRAM MANUAL
Some head-scratching and a quick perusal of the manual is required. They're obsolete.Īt this point I'm gifted another identical Dual amp with a fault! The output transistors are swapped out of this amp, and set up again. Spraying the Left hand output transistors restores operation. Out with some freezer-spray-on- the-cheap. A low rumble is apparent in the left hand channel. It's set again, and something's obviously wrong. After a few minutes, the bias is checked, all is not well. Switches and pots are duly clean ed up, the bias set, and the amp put on test. Thankfully Dual provided us with a nice access panel on the bottom, making repair a breeze.

so they're evicted, the board cleaned up with some IPA, and the caps replaced with some nice new ones. Off with the lid, and a few issues are immediately apparent. It's a Dual PA5030, a good quality hifi amp from around 1988.
