Garrard record player deck identification.

[D_S_J_R]

I remember being confused by some SP25's with steel outer/top platters, but I suspect these were cheaper OEM models supplied or fitted with ceramic cartridges, so the extra magnetic field wasn't an issue. I don't recall the MK3 version being supplied this way, but could be wrong.

I've recently 'rediscovered' that the larger SL72/75/95/AP75/76/86/96 etc. and Zero chassis' used a clever little rubber O ring on the bottom of the inner platter hub, just snug against the geared part, for helping the mechanism to run as quietly as possible. Works well too - 13mm x 2mm for the 86SB and possibly the same large diameter but 1.5mm cross section for the idler models (I'm awaiting delivery of a few). Dual and B&O used a plastic or delrin main gear and lighter acting levers (one main one with the Dual), so run very smoothly in any case, the 701of mine being almost silent.

The slickest of my auto Garrards is the Zero 100 I have. The mechanism runs quietly and the metal tabs function well, without the 'thunk' action of the plastic ones fitted to the others. Why did Garrard have to penny pinch so much on the fine details, where the jap auto decks of this period were mostly crude and horrible underneath, yet with a superbly done finish on the exterior (Techie SL1300 and auto relatives excepted, which were slick and very gentle on low-force trackers I remember).

I have owned 2 SP25 Mk3s, one with an aluminium outer platter in a PYE G73 Black Box fitted with a ceramic cartridge, unfortunately this went about 30 years ago. The second was in a Dynatron HFC38 Music Centre with a steel outer platter and fitted with a Goldring G800 magnetic cartridge. I have only just acquired this and was surprised to see the steel platter.

Whilst it may not be preferable to use a steel platter, the fact it was used with these
decks is the Garrard 4-pole motor has a low hum field. The field leakage with the
cheaper 2-pole motors (esp.BSR) makes them unusable with magnetic cartridges.

[D_S_J_R]

Another little tweak I've been banging on about on Vinyl Engine regarding the AP76/86SB and all other related models using this basic chassis. On the platter's inner hub just below the toothed part (that engages with the cam), there may or possibly should be a rubber o ring which breaks up or turns back to tacky liquid (or both ). The mech is truly silenced when a suitable o ring is fitted here - 13mm x 1.5 for the earlier models and 13mm x 2mm for the 86SB (and by inference, the Zero 100SB too). I don't have an early AP75 or SL75/95 to hand, so cannot reliably say that these are the same, but examination will show if there's a tell-tale groove just under the geared part on the inner turntable hub.

No such item is shown on the exploded diagram in the service manual of the SL95/75 or the SL95B/75B; nor for the Zero 100, 100C, 100S, 100SC.

It IS shown on that for the 86SB/Z100SB: Callout No. 59, Part No. 73139, "O-Ring."

[D_S_J_R]

My AP76 had the remains of one, which I had to scrape away and there is definitely a groove around the bottom of the geared part where the remains of the o ring was seated..

I hope this is OK on this thread - I recently stumbled across two old pictures I captured from an eBay USA auction a few years ago and have attached here.

The deck was advertised as a Garrard AT6 but you can just about make out the lack of model number ID plate on it and I've never seen an arm like this before or since! Does anyone know anything about it?

[unitaudio]

I've never seen that arm before either. Probably made for a specific manufacturer to include in their equipment. Garrard were very popular in the U.S. and made loads of such "specials". Customers included Realistic (Radio Shack/Tandy), Sears, even K.L.H., Scott and Harman-Kardon. A garrard deck was often used as a major selling point in advertising of the period. I think that's the kind of thing in the pictures.

...Come to think of it, the overarm on that one is a bit different to the normal U.K. models too.

This part was also fitted to the later SP25 models, it's listed as item 138 Part No. 73139 "Cushion ring" on the exploded diagram for the SP25III.

Most seem to have perished over the years.

Something completely different, the little BA1 deck which was fitted to various pioneering battery powered transistor portable record players in 1956-7. These photos are from Cossor's offering, the 544: others included Roberts' Mayflower and the Vidor CN438 Jamboree. None are at all common and problems with speed stability may have been the major reason for their limited distribution. At least in this version the BA1 is powered by a 9 volt battery with a series 80 ohm rheostat to govern its speed. The cartridge is Garrard's own GC7.

Like the turntable itself!! A wonderful thread.
This is my everyday player. I had to change the bearing when I got it.
It did about 35 years service in a radio ABC studio before I got it.
I need a new idler wheel now after 15 years service for me.
I was wondering if anybody has found a source of new idlers
that dont cost 100 quid or more
The plinth is my creation. Its two inches of aussie slate held up by
one inch thick New Guinea rosewood. It weighs three trusses and one hernia.
The arm is one I have had since about 1966. I have another the same as "spares". I also have a couple of V15 MK III HE's but I find it near impossible to find stylii for them.

Here is my wind up Antoria with its Garrard model 20 1930s wind up motor.

[Edward Huggins]

An addition to the Garrard model variations maybe? Towards the end of the production run of the Pye "Achoic" Model 1005 Stereophonic record player (c.1963) they installed a version of the Garrard AT6 with a special arm for the "Butterfly" stereo-cartridge. There was a Butterfly legend at the pivot end of the tone arm. I cannot quite remember if this ran alongside the modified BSR UA15 version. It would certanly have needed a different cut out. I suspect there was a short production run as I have only ever seen one. Alternatively, it may have followed the UA15 in 1964 when BSR introduced the UA25 unit, and Pye decided on a better quality deck. Edward

That seems highly probable, Edward. The UA25, with it's flimsy plastic arm and controls, was certainly a drop in quality from the UA15!
