ax17 bisa set

Nice work, but go to PSU15 with mosfet outputs.

hi mr mile.i made ax17 with 2pair mj2955/2n3055 and +35/0/-35
rail...what is the best bias voltage?
and i too made that with 2 pair mj15024/mj15025 with +50/0/-50 volt rail...and what is the best bias for this in ab class?

Hi Folks,
I have asked JPS64 to work up a new layout for the popular FH9 using all the latest tricks of the trade from a professional designer. We will make it based on the FH9HV and have certain component upgrades and things to make installation easier. It will be called the FH9HVX. Stay tuned...
Cheers,
X

Still4given, you threw that one in to confuse us, right


These have to go on heatsinks, seeing that it can supply upto 10a. Was just wondering how you guys did your build with this PSU10R

Here is a better layout for using TO3P outputs so they can be attached to heatsinks.

Still4given, ur a master with this, thank you. What program are you using to get these? I havent tried to do any layouts, but i would like to learn. From taking a schematic and getting the end result like your pcb's

I'm using Sprint-Layout 6.0

I had some help from a few of the guys here on the forum to get me started. I am much better at editing layouts created by others than creating them myself from a schematic. Prasi amazes me at how quickly he can come up them. He uses Eagle. I tried that but just couldn't get my head wrapped around it.

I had a laptop fail on me and I lost most of my macros so I am gradually recreating them.

Im going to give Sprint Layout 6.0 a try, thank you. I actually have it, but stumbled right at the begining and just left it. It gave me headaches

Hi X,
Looking forward to how the new FH9HVX turns out,sounds like a
Great idea indeed.

Another FH9 soon to be born

 

[xrk971]

Very nice, Vunce! Dale’s, Takman’s, and Panasonic ERX’s! Way to go!

 

[Vunce]

Thanks X
I threw everything I had on hand to stuff these guys!
Hopefully tomorrow I can drill/tap and get the mounted on heat sinks.

best wish for you.
psu15 work at 40to 70 volt ac...my transformer is 25 volt ac....it have problem or no?

Use 8V2 zeners instead 15V

PSU15

Hi Mr. Mile,
Can I use PSU15 to drive a pair of A40 amplifiers? Transformer would be 45-0-45 volt AC 12Amps. Output regulated to 55-0-55 volt DC.
Could you please advise.

Thanks
Sha

Hi all,
What the correct arrangement for buffer and volume pot?
A or B?
or have better idea?

Hi, for me the best arrengement is B, buffer with pot

Thanks,But i found some noise using this arrangement
