Re: Regentone Compact Radiogram
The Studio "O" was one of the very best Crystal cartridges. It's possible to buy a stereo stylus for this as a direct replacement, but vertical compliance will be very limited. Edward

Re: Regentone Compact Radiogram
well done that man.
The main problem I have seen with these is that the plastic surround to the tuning scale cracks but other than that they are very reliable and considering they have a smallish speaker give very good sound. Steve |

Re: Regentone Compact Radiogram
Regentone seemed very keen on the number '99'. I have another floor-standing version here, clearly stamped ARG99C on the chassis. Never seen another, nor any service data for it. It has a Garrard RC72A changer so must pre-date most of the other '99' models. Now fitted with a Collaro Studio T cartridge, which seems as good as new after more than 60 years. RC72A has the 45rpm speed but no way of playing 7" records, unless I have missed something...?

Re: Regentone Compact Radiogram
The Collaro Studio "T" is the wrong cartridge to use in this model as it is a (very) high-output type and will swamp the AF stage with a full 1.0 volt of output! However, it is very rare and worth a lot in its own right. Owners of faulty single-stage portable record players will pay the earth for one of these! Edward
PS Do you need the large centre hole 45s stacking spindle? |

Re: Regentone Compact Radiogram
Thanks for the advice, Edward. The ARG99C gram input has an impedance of 470k and there is a series resistance of 560k in the headshell to bring it up to about 1M, so there is some attenuation, and it seems to work fine without overloading. I imagine the original would have been a Garrard GC2 or similar.
The RC72A seems odd to say the least. It has 33, 45 and 78 speeds but the platform that nudges the edge of the bottom record on the stack has positions for 10" and 12" discs only, so 7" records cannot be stacked. There also seems to be no way to operate it manually, as the change cycle starts as soon as it is switched on. The only way I can see to play a 7" record is to place it on the turntable manually, allow the pickup to drop in the 12" position, then move it manually to the edge of the record. The turntable is only 10" in diameter so no harm is done, but it seems a particularly clumsy way to play a record. Perhaps it was released as an interim model while a three-position platform was being developed. Roy |

Re: Regentone Compact Radiogram
Tne original cartridge used in the BSR UA6 autochanger in your "99", is most likely to have been an Acos GP37-1 turnover crystal cartridge. Edward
