Citation 12 complimentary MosFET version PCBs

[Tazzz]

Hello,

I have a few PCB's left over from a restoration I did on a totaly wrecked Citation 12.

See attached files for schematic capture, pictures and some performance measurements made on the built amplifier.

I want 22€ for a pair of boards including shipping to anywhere in the world.

 

[Tazzz]

Forgot this, Citation 12, 1kHz, 1W, 8ohms.

 

[Tazzz]

Still some boards left if anybody wants to build an incarnation of one of the Classics this summer.

 

[Tazzz]

Down to the last two sets.

 

[MEGA_amp]

I'll take a set, shipping to US

 

[evette]

Could I order a set. Evette

 

[marc brown]

Are there any left? If so, pls PM me.

 

[citationfan]

Are there any left?
If so I would like to order a pair too.

 

[Tazzz]

I shall take a look, send me a PM.

 

[Tazzz]

I just found two remaining sets.

Hello Tazzz,
Do you have a pair of matched 2sa970 for sale? One transistor got lost and I don't know how to find a match for the single one I have. Any help would be appreciated.
Regards,
David

Send me a PM.

Due to a recent upsurge in demands I have ordered a new batch of PCB's for this very good old amp.

Thus PCB's are once again availble.

Hi Tazz,
Bias setting is always a scaring point for newbie, at leat for me..on your schematic and pcb it seem clear but I would like to be sure:
If I understand Right, At the initial Turn On the screw of the variable resistor R17 must be in COMPLETE COUNTERCLOKWISE position?
and what final bias you've got?
I've read too many contradictory information, I prefere to ask simple and useful questions.

Hello,

Do you have any PCB's for the citation left? I would like to purchase a set from you if you do?

Regards,

Larry

Hi Tazzz, guess quite late in order, I am looking for a set of Citation 12 PCB's...any chance for me. regards/Kamal

Kramskee has boards if Tazzz doesn't, though they're for a new build rather than retrofitting an old amp. If you have an old amp they can be adapted without too much difficulty using the old boards.

Thanks, is there a schematic change as well for the new build??

 

[schubert]

The complementary mosfet version is different than the original circuit, yes. From what I understand Tazzz's boards will fit in the old amps, whereas Kramskee's don't. Kramskee's boards also have places for power supply caps.
