Regentone Handygram
New member 😉
I have no tech knowledge whatsoever Site search has reveled this model is still unidentified. Parent house clearance after bereavement. Stored internally. Totally dry no damp. Overall condition looks good. Understand parts can be hard to source & some obsolete. Starting point, powering up, unsure of positive/negative from 2 core wiring to test for basic operations. Perhaps then we can decide on best to progress. Last edited by SteveMel; 17th Jan 2021 at 7:00 pm. |

Re: Regentone Handygram
This record player dates from around 1957/8. if the two core wiring is Black/Red then black goes to negative, red to positive. If there is no colours in the cable then you can connect it any way round.
Before you do so however there almost certainly be parts inside that need replacing, also this record player might have a 'live chassis' Open it up and look at the valve types, come back here and tell us and we can advise you further. DO NOT APPLY POWER TO IT BEFORE CERTAIN CHECKS ARE MADE AND CERTAIN PARTS HAVE BEEN REPLACED. |

Re: Regentone Handygram
It might well be this one :
https://www.vintage-radio.net/forum/...d.php?t=151648 If so it has a multi-stage amplifier which is good news. I think we need a peek inside. Cheers Mike T

In addition to Michael's excellent advice, if you do decide to fit a mains plug, it must have a 3A fuse (red) in it, as opposed to a brown, 13A one. |

Black to negative, red to positive would probably cause some interesting results. Black to neutral, red to line (live) would be the correct code for the old style wiring. Looking at that lead shown, I would suggest it has been wired shorter to line, longer to neutral. At any rate that would fit a 13A plug better. As has been mentioned, either way round will work, one way might be slightly safer or result in less hum.

Re: Regentone Handygram
I think this model either uses either a 3 stage amp, 2 x UCL83 in PP and a UY85 - OR - a 2 stage UF89 and UL84 + UY85 unit. This means it is liable to have a "live chassis". Before firing up, the mains lead wiring should be tested with a continuity tester to estabiish that the "neutral" wire of the two goes to the chassis. The OP should also be aware that (as it stands) this player is not suitable for use with Stereo LPs (and most LPs are) until the cartridge can be changed. If the OP is uncertain about taking this on, it can be succesfully repaired by a local specialist and any parts that are needed are still available.

Re: Regentone Handygram
According to the thread linked to in post #3 the valve line up is UF89, UL84 and a UY85.
Let's wait to see if the OP confirms this.

Re: Regentone Handygram
Wire are not colour coded as shown in the pic, having spoke with sparks before I got back on here he advised polarity should not be an issue, wired it up with a 3amp fuse it do power up, changed to a 5amp again powered up, I also put a 45 record on, runs a little slow revolution count was circa 38 with the selector on 45, stylus also works though sound quality hard to assertion with revolutions out.
To see what's inside I don't know which screws to remove . 4 outside of cabinet, 2 securing turntable for transit? 4 to the outside of the turntable as images. |

Re: Regentone Handygram
Which screws need removing to expose the chassis.

Re: Regentone Handygram
The light coloured panel adjacent to the deck appears to be secured with two screws. Removing these should allow access to the amplifier.

Re: Regentone Handygram
So far deck is free, 4 screws to panel removed also two longer screws to the outside caseing, inner panel is not free.

Re: Regentone Handygram
Managed more force than expected.
Now really am at my limits no knowledge of using test meters Etc. Unless any of you peeps spot anything the only known is the deck is running slow. 🤔😁 |

Re: Regentone Handygram
It looks as though that has a mains transformer which should mean it is an isolated chassis. I have found the circuit for one Regentone Handygram (AHG.4W) which has UBC41 UL41 and UY41 valves and has an isolated chassis

Re: Regentone Handygram
It's most unusual to see the amplifier/speaker compartment sealed off like that. (Heat build up, poor acoustics?) This looks like the UF89, UL84 version with a mains transformer. We do not know if this is fully isolated or just a filament transformer, and yes, Regentone did use these with "U" series valves. The low speed might be debris built up on the (stepped) motor spindle, hardened grease or a partly seized platter. When working on this it will be easier if you lock down the autochanger deck plate down using the transit screws. Wnen it comes to DC voltage measurements, it might be best (and certainly safest) for an expereienced person to check this over for you. Your unit is now 63 years old!

Re: Regentone Handygram
Looking at the photo's in the link in Post#3 it looks like it's an isolated chassis, the mains transformer secondary supplying the feed to the rectifier and supplying the series heaters via a dropper resistor, the one in that one is a 200 Ohm job, that along with the heaters would tally up to approx. 115v, in those photo's the dropper resistor is connected between pin 9 and pin 5, the red wire from pin 9 (anode) going to the secondary of the transformer.......So far as I can make out.

Re: Regentone Handygram
Thanks for all the help & advice.
In current state any valuation, we've decided selling is our preferred option as we have no vinyls in any case. Last edited by SteveMel; 18th Jan 2021 at 8:40 pm. |

Re: Regentone Handygram
OK. Given the amount of work that is likely to be needed, it's age and the fact that it cannot play Stereo LPs (as it currently is), you might List it for £30-40 and see what offers you get. I can say that, when fixed, these players do sound very good.

Re: Regentone Handygram
Whatever you decide to do with it, bear in mind Michael's advice and don't apply power again. You could well burn out components which would cost more than it is worth to replace
