Default Trio JR-500S schematics / manual required.

Does anyone have a manual / copy of a manual for a Trio JR-500S receiver. I'm particularly interested in the detailed schematics 'cos I need to repair mine. Anything considered: paper, jpgs, pdf file, etc.

Thanks,

Dave

Take a look at this thread:-

https://www.vintage-radio.net/forum/...ead.php?t=2005

A quick Google search on "Trio JR-500S" brings up several sources of information, at least one of which is free.

If you google around a bit you may find somewhere where you can download the maker's manual for free.

Thanks for the advice, Graham. I did quite a bit of searching around the net before I posted the request, and, apart from the hand-drawn schematics on one site, no joy. I was really after an alignment sequence as well.

Still, I'll keep looking.

Regards,

Dave

Hello Dave,

just came across this forum in the last few minutes. If you're still after the information let me know and I'll e-mail the info.

Les.

Lowe Electronics have original service and installation manuals for this set,
but they will charge a modest amount for them.

They were the original importers of this equipment and have other manuals of this vintage too.

Give them a ring on 01629 832374

Hi fellows,

Thanks for the responses. Sorry I'm a bit late in replying, but I have only just started finding all my favourite sites after a PC migration (there has to be an easier way!!!!).

Les, check pm.

Regards,

Dave G0MXD

Dear Dave.

Do you still require the schematic for the JR-500s ?
I have a manual that has one page of alignment instructions.
Please reply if you need.

Hi Labrat,
still having problems with the PC I'm afraid.
Thanks for your offer of help, but Stonehenge (aka Les) has furnished the required circuits + setup info. I am now in the process of tweeking, but don't want to rush it!

Thanks,

DAve G0MXD
