F5 Point to Point Power Supply Schematic
 
I'd like to point to point wire my F5 power supply... Can anyone supply a schematic for one? One you've actually used?
Thanks so much,
DB

is this a standar F5? how many caps are you planning on? is it dual mono supply or one supply for 2ch.?

It is a standard F5... I would like to go dual mono on the supply.
Thanks,
DB
P.S.
Family came from Gaupne on my Dad's side, LilleHammer on my Mom's.

Why not the one from the F-5 service manual?

oh:)
you can use this one. insted of 2.2mH coils, you can use resistors.
0.2ohm 25W power resistors, or pack of 4 1ohm 5W in parallel.
and you can get away with 6x10.000uF 35V caps.
and a 2x18V 200VA-300VA transformer pr PSU.

ALEPH 3 POWER SUPPLY

I don't know about a F5 service manual... I'm building the amp up point to point from the schematic in Pass's article.
The F3 supply looks solid.

its aleph3:) but yes it is:) i use the same with a more beefy cap bank on my aleph2's. and it works wonderfull:)
also doing the same for my F5 right now. but that ones are on PCB's.

If I use the 6 cap scheme where should I locate the resistors/chokes? After the first pair?
Thanks.

AudioSan 22nd February 2012 03:16 AM

after the first pair or sec pair. its up to you:) some says after first pair is the best.
others says it does not matter.

oh. forgot one thing. 2.2Kohm 5W resistors in parallel with the 4.7uF caps(2.2-4.7uF is good).
that is to bleed down the cap bank after powering down.

Cool. Thanks.
