Preamp ideas for F5

[AudioSan]

[biju55]

is this one a good preamplifier for F5 ?

 

[Zen Mod]

no

 

[biju55]

can you tell me the reason .... why not ?

 

[Zen Mod]

not same league

besides , you posted just half of preamp sch - PSU is of same importance

 

[biju55]

can you tell me , the best pre-amp for f5 ?

 

[Zen Mod]

look for Juma's threads , for instance

Juma's preamp for the F5 is found in post #53 of this thread --

[Zen Mod]

yup

I just realized that we are in that very thread

😉


but , if I'm not mistakin' - there are few more from Juma , floating around

Or twice the Juma circy, with volume attenuator inbetween.
Hey, and switchable gain, as in Biju55's drawing.
Hey, and with surface mount R's on a piece of copper clad board, with 8 pins sticking out.

i'm very happy with aleph P1.7 as preamp for my F5 🙂

 

[jacco vermeulen]

Don't let anyone tell, you do not have a sense of humor.

well worth looking for

I dont doubt the pumpkin at all, although i think Juma's Schade circuit might pair nicely as well.
