Wow, I'm on a roll today! LOL
For sale is my combo AMB a10 with balanced JC-80 modules
This project is located on AMB's forum but also here:
Preamplificateur AMB α10 version balance avec modules JC-80
It is a balanced preamplifier using the following parts :
- JC-80 clone PCBc using 2SK389/J109 as input, 2SK2013/J313 as output but also as regulators. Resistors are a mix of Dale, TX2575 (foil), Caddock TF and MP series. Caps are also all good quality, ClarityCAP MR, and electrolytic are low ESR for the PSU section.
For volume and source selection I'm using the following
- 2x AMB δ1 ("delta 1") - R2R shunt ladder
- 2x AMB δ2 ("delta 2") - Source selector
- 1x AMB LCDuino-1 with LCD
- 2x AMB α10 backplane ("alpha 10")
- Onboard PSUs are 2x AMB Sigma 22
- Transformers are in separate chassis and shielded.
- Remote learning capability, volume for each zone is retained, source labeling and possibility to assign any input with any output.
It is currently configured as follow for inputs / outputs
- Inputs = 3 balanced / 2 unbalanced
- Outputs = 2 balanced / 1 unbalanced
Front and rear panels have been done at FrontPanel Express so it really looks professional.
I'm asking 1000$ negociable
Thanks
