Hello,
There are three ways to power the 82, with one, with 2 HC or with a SC.
I tried to understand the difference that those combinations may have on the internal powering of the "parts" (TA, Gain, Tape and Phono) of the 82.
I suppose that the NAPS powers the remote parts and the display (anything else ?) and will let it apart in the following.
A) Connecting the 82 to only one HC, I suppose that the power-grouping is similar to the one of the 72:
- 1st 24V rail: Gain (321) + Relai
- 2nd 24V rail: TA (729) + Tape (324) + Phono
B) When a second HiCap is added, do we have then:
- 1st 24V rail: Gain (321) + Relai channel L
- 2nd 24V rail: Gain (321) + Relai channel R
- 3rd 24V rail: TA (729) + Tape (324) + Phono channel L
- 4th 24V rail: TA (729) + Tape (324) + Phono channel R
Right
If yes, this configuration (both channels powered separately) need certainly a modification of the 82-internal wiring ?
C) Going to the 82 + SC:
- are all cards now powered by a single 24V rail as in the conf. 52 + SC ? ??
Is there any quality difference between the HC and SC concerning the regulation (apart their number of course) ?
They are all based on the LMT317, aren't they ?
Thank you a lot in advance
Olivier
