In Reply to: RE: Single PSU or dual mono best in amps?? posted by Mike C on June 18, 2012 at 11:41:51
Assuming three stages in an amp, and splitting the PSU between stages - if you use two PSUs, do you have:
1) One PSU for output and another for input and driver
2) One PSU for output and drivers and another for input
Could do it either way - what do you think?

Hi Andy,
a good choice is only possible in the context of the design.
This is like asking which are the best tires for a 4 door car ;-)
Depending how sensitive the stages are against interaction either of the choices can be better. Fotr example this can depend on teh amount of voltage amplification in a stage and wether it flips phase or not.
Best regards

Hi Thomas,
As regards design. My regular design is all-DHT, in fact I only use DHTs unless customers want something else like 6SN7 into 807.
I've buit 300B SETs with 26-46-300b
Currently PP 26-4P1L-2a3
First two stages are usually direct coupled.

Hi Andy,
now we know your car has 4 doors and a naturally aspirated engine ;-)
The funny thing is, if you would ask such a question on a car forum, you will most likely get responses with specific recommendations and how they will impact the driving of your car ;-)
Best regards
Thomas
