Hullo Nate!

Sorry for slow response, i´m not very active here at diyaudio at present since i´m professionaly involved in the audioworld as a loudspeakermanufacturer.

Yes.

No.

The original was good for 40 years ago, the complementary Mosfet
version is better.

building one too

Kinda late in posting. I am wanting to build a mosfet version of the citation 12. ingvar ahlberg, I emailed you. Hope boards are still available. I hate laying out boards. Mine turn out so big. My plan is to use 2n5551 and 2n2401. In the motorola book, these are prefered transistors. Also using the IRFP240 and IRFP9240. I am very anxious to build one. I did find the complementary schematic. I have the citation 19, 17 and 16. I like the sound. I did build the PASS 40w class A amp. Sounds very good too.

Reviving MOS CIT 12.....

Finished my amp....

Own board design, Parallel outputs, Mosfets are from used SMPS. Quasi type since no available P channel. Most parts are salvaged from junks....MY WAY OF RECYCLING>>>>>>>

Amplifier at work for a year now with no problem with the sound. Not the best looking project especially wirings but enough for personal use. Now borrowed by a friend and tortured..
