Finally finished (for now) a rebuild of a C11 that I got 10 years ago. Thank you for all of the "giants" on Audiokarma that did this before me. You guys inspired and taught me.
I divided the rebuild in 4 phases. Performed listening tests the unit after every phase to determine whether each function was good.
The final result exceeded my expectations. Many pluses and some minuses comparing its sound to my other preamps. The tone and transparency are very very good.
Resistors mostly from digikey
Capacitors from partsconnexion. I used JANTZEN Superior Zs and Sprague Orange Drops.
1. Power Supply ; using the CTECH deluxe kit.
2. RADIODAZE relettered bottom front panel.
3. Line / buffer Stage: all parts surrounding V6.
4. Tone Amps: Parts supporting V4 and V5.
5. Phono Stage.
6. Increase B+ capacitance to 770uF.
In the near future.
7. Replace the remaining resistors.
8. Replace RCA jacks for R&L output channels.
9. Replace RCA jacks for line level inputs: AUX, TUNER1, TUNER2, TAPE.
10. Replace RCA jacks for PHONO 1 and PHONO 2.
