Rogers Cadet III Schematics

needlesview · 15th November 2004, 07:35 PM

Help!!

Does anyone have or know where I can get hold of schematics and a service manual for a Rogers Cadet III integrated amplifier?

G'day from Down Under,
The parts list and schematic are on the last couple of pages of the User Manual. I don't think a Service manual exists.

Do a search on "vintage hifi manuals" or similar. I bought my original copy of the manual from the UK for 5 pounds.

As I was doing a full restoration I thought it was money well spent (especially as I had to pay 20 pounds for ECC807s to finish the job).

If you have no luck then email me and I'll arrange to get the manual photo copied and will post to you. Note the schematic is one of those with no component values just component numbers - you WILL need the parts list as well as the schematic.

Cheers,
Ian

Hi needlesview,

Strange as this may seem, I have a set sitting on my desk right now. Since I seem to be getting regular requests for these schematics, I thought I'd best do several copies the last time I was asked. Drop me a line via the link below.

The parts list is on the back page of the manual. I can also send schematics for the PU adaptor to be adapted for magnetic pickups.

I posted a diagram of the power amplifier on this forum. This is rather embarrassing; although I can find it by doing a search for Rogers Cadet and putting EC8010 in the user name of the search field, I don't seem to be able to cut and paste a valid URL. The diagram is on the second page of the "Suitability of ECL84 tubes for audio" thread.

Hi EC8010,

My wife likes your avatar, is the cat one of your own?

EC8010 · 20th November 2004, 08:31 PM

Yes. She's Anode, and her sister is Cathode.

SuppersReady · 20th November 2004, 09:35 PM

Further message from wife: She thinks the names are brilliant. Presumably they are complete opposites in character.

Based on this we should perhaps rename ours as Gate, Source, and Drain. Might sound a littte strange when calling them in at night though...

EC8010 · 21st November 2004, 12:13 PM

The names were given by a friend who drove the kittens 30 miles to me. Cathode yowled continuously the whole way, so he named her that because she was such a copious emitter of noise. After that, Anode followed on naturally. I couldn't think of better names, so they stuck. I once had a cat called Geronimo. You try shouting that at the back door and see how silly you feel!

This is the schematic i did for a previous thread -- with input from EC8010 -- i think i've gotten all the bugs out of it

Thanks for that, Dave. Apart from the 999V across the 450V electolytic, it looks fine!
