Upgrade wanted for Acos GP 93
I have bought a 1968 radiogram with a Garrard 2025TC turntable, and I am looking to replace the Acos GP93. Any recommendations please?

Re: Upgrade wanted for Acos GP 93
Hi, and welcome to the forum.
Is the Acos faulty? If not, I'd leave well alone. The arm on the 2025TC, having a ridiculously thin headshell, is very difficult to fix a different cartridge to. The Acos GP93 cartridge has a mounting clip that was specially designed for this arm, and the only other cartridge with a similar clip was the Sonotone 9TA, which is obsolete, and even if you managed to find one, would be unlikely to have that special clip. |

One of the Sonotone / Garrard 25xx / 35xx series cartridges will fit this turntable if you have the slim mounting bracket. The Stylus Lady often has the cartridges and clips in stock.https://www.thestyluslady.co.uk/narr...s41b-622-p.asp

Re: Upgrade wanted for Acos GP 93
I completely agree with this advice. It is highly unlikely that you would hear any sonic difference by fitting anther cartridge. But it is well worth checking the stylus under 12X or so glass and, if necessary, replacing it.

Sorry I haven't replied to your post. The cartridge has a faulty rubber piece that the stylus head rests on. It has lost all rigidity, it plays for a while and then slowly drops down again

Re: Upgrade wanted for Acos GP 93
This being the case, I would go for a BSR SC11M whilst stocks are available.
I would not call it a real "upgrade," but it's certainly a replacement. Do make a diagram of when the 4 connectors go ie. RH+, RH-,LH+, LH-. But before resort to this, what do you really mean by "drops down"?

Re: Upgrade wanted for Acos GP 93
I know what the OP is saying. I have had many GP93 carts lose solidity in the rubber mountings. The cart body thus ends up dragging on the disc. Only real solution is a new cart.
To the OP: Don't remove the bracket for the Acos, with some modification and glue the SC11/12 may be made to fit it. I have had good results with the generic Chinese ceramic carts available for a pound or two on ebay. The sound quality is usually better than 40 year old ceramic carts, even those that are NOS.

Re: Upgrade wanted for Acos GP 93
cheers Ben.
Edward, The saddle that holds the head of the stylus droops, for want of a better, word thus causing the cartridge to touch the record. |

Re: Upgrade wanted for Acos GP 93
If you are convinced that there is a "structural" problem with the cartridge, then you may have to replace it with a currently available equivalent as suggested earlier. If the saddle has perished/hardened, then it may have lost its grip within the cartridge assembly. It's a fault I've never comes across in over 50 years.
