I should prolly PM you 'cause this is way off topic, but your chessboard is one of the most beautiful examples of woodworking these eyes have ever seen!!

I have the service manual for the RCD-02 if anybody wants it. It's about two megs pdf, so I'll email it to you.
Cheers.
P.S. I just phoned Rotel (NA) and they emailed it to me.

I just bought (it's already shipped) a trichord clock 2 with a 11.2896 MHz crystal.
The service manual specifies a 16.9344 MHz crystal.
Anybody know whether or not I can swap the 11.xx for a 16?
If so, anybody know where to get a 16.9344 MHz crystal of quality?
Thanks.

Hi The Trichord is not using a crystal but a crystal-oscillator contained in a square metallic boc. If you want to use Trichord exchange it at the factory. Maybe they are willing to do so
Thanks Elso.
I will pursue that route. Glad I asked!!
I would prefer to build one of yours, but I must wait until I develop the sufficient skill first.
Just out of curiosity, how would you compare the Trichord 2 vs. yours?
-I hope that question is appropriate.

Well, as it turns out, my old CC-52 that I gave to a friend has the correct Trichord 2 @ 16.9344 MHz. He's got hearing aids, so he didn't mind if I put the old crystal & caps back into it.
So, if you're interested, I could send you the 11.xx one when it gets here.
I have no use for it and it would be useful for me to know what you think of the Trichord 2s.

I would say if the service manual says 16.xxMHz then that's what it is, I wouldn't trust my memory!!
Cheers for the compliments on my woodworking! I'm building that chessboard to go in a gallery, but I dont think Ill be able to part with it 🙁

If it's any consolation, I'm stuck in a 3' crawl space below my house painting baseboards & cabinet doors. 🙁
I started an RCD-02 mods thread. Could be interesting to see if anybody has some ideas and how many people actually have this CDP.

Just a thought, would it be theoretically possible to replace the crystal oscillator (XO) on the Trichord with a Tentlabs XO of the appropriate frequency?
theoretically
Practically and theoretically yes, you could even fit in a KWAK-CLOCK hahahaha😀

baggysteve, did you ever find out the mystery of your voltage in the digital section. I'm looking at the schematics and if I've understood well, there's +10.3V before regulator U901 but there's no -ve voltage to be found.
Is this really a single supply in the digital stage? 🙁
... I am myopic...maybe that's it.
Cheers.

Hi,
Youll have to excuse me bein lazy, im a bit rushed off my feet at the minute. Cant really trawl through this thread to find out.... wasn't it my analogue supply that went funny? I've ignored it anyway and it's been fine for the last few years, certainly something I ought to fix really though! hehe

Re: BC550C
I'll agree that without tools it's very easy to damage the pcb but is it more diificult to make them? You don't do them by yourself? 😕
Making a homebrewed pcb with groundplane is pretty easy, just put tape on the groundplane side. After etching just drill out the holes which are in contact with groundplane.
.. just wonder why considering the easyness of repairing your product? It's better to do the design reliable instead so you won't repair it?Elso Kwak said:

An externally hosted image should be here but it was not working when we last tested it.
Is there anyway of adjusting the square wave without using an oscilloscope, I do not have access to one.
And also, when I hook up the KC, do I have to put a resistor in anywhere? I vaguely remember hearing some such thing.
