Dynatron GR5 espresso record player
Just dug this out after a few years of storage. Searches have turned up nothing for this, the GR5. Nice unit with proper bass and treble, and a collaro studio deck.
Seems to be one of their earliest models, anyone got any info? Not an urgent request, as it works well, but I would like to get hold of a schematic in case I go for a restoration in the future. pics attached.

Re: Dynatron GR5 espresso record player
Odd deck that one, seems to use a conquest arm on a studio deck. With the later studio arms you could set tracking weight.

Re: Dynatron GR5 espresso record player
Thanks for the responses.
I will try to open it up and get some pics of the amp, There are at least two valves in there I can see. I might have to replace THAT capacitor.

Re: Dynatron GR5 espresso record player
Thanks to Jon and the manual, this is now running well. I changed three 0.022 caps, one was wax and two Metalmite cp33. Will add a few pics in due course.

cart is a Ronette 284, still works very well. I might start a separate thread on the ronette stylus markings though, they`re like hieroglyphics!

Re: Dynatron GR5 espresso record player
Just to add to the melee. Dynatron made a matching tape recorder, model TPR1, using the Collaro Mk2 tape transcriptor.
I assume this is the same vintage as the 3 band transistor with the twin telescopic aerials for vhf, presumably going for a younger customer with all that trendy vinyl! Rick. |
