F-5 parts question?

semi932 · 11th May 2011, 07:55 PM

I've got the boards form this site Cviller type and have got my Mouser order together but just have a couple parts I'm confused about.

Any suggestions for the 5k trimmers?
There are so many Bourns multi turns that I can't seem to figure out the difference and which will fit.

Also I ordered this for thermistor NTCLE101E3472SB0 Vishay/BC Components Thermistors - NTC

Do they look like the correct item?

Thanks for all help.

As an aside I can't believe that I ordered the boards on Sunday evening and already received them on the east coast of US.

Thank you.
Very informative to say the least.
I've done a lot of searches on the forum but just couldn't seem to get the right threads.

Never thought to check blog.

Appreciate the help. Now to get everything together.

Everthing is good except a real problem with Mouser for jfet p chan

Tried 2sj74-2sj108 and search for 2sj in general.

Closest I got is not available on 2sj74.
Any suggestion?

It's all I'm missing.

Hi Semi932
Blues got me a few sets of matched fets for my F5
Nice chap and quick and in your side of the pond.

For trimmers I went for 1.25 Watt multi turns and you may reduce R3 and R4 from stock values
Gives you a bit more turns on the trimmer and less current trough it

I have not decided on the values at present I have 600 Homs instead of 2.2K
With the Toshibas
Running 26 V rails at 3.5 A

Holco MFR 15ppm 2W for sale

All helpful responses.
Those j's are getting tough to come by.
I'm checking all the avenues I can take so kind of going slowly but at the same time I'm anxious to build cause of all I have heard.
