Just a newbie here... Can anybody the proper way to wire the transformer to thermister to the rectifier? Thanks!
Re: Re: recommendations??
I think 300 VA or more is recomended with the F5. Some are using a 400VA Antek. I plan to use the Plitron 300VA 2x 18v. I don't know what difference using 17 Volt will make. Not much I would think.

I'm not sure exactly what you're asking. I think I'm going to use a terminal strip to wire up the two primary windings to the thermistors and the cap, If that's what you're asking about.
It may have been easier if the thermistors were on the PS board and you could solder them on but Cviller thought is was better to keep the AC away from the DC.

The Thermistors I think your discussing are not connected on that side of the transformer. They are wires from the AC side of the transformer. If your on 220-240v, just wire in series with the hot side. I use a terminal strip or a euroblock and use the thermistor to wire the two points together.
I will try to set up a site for taking the orders, but in the meantime you can just mail me with the orders and I'll put you on the list.
Hi
Is 63V Aerovox ALS30 overkill? . Not to fit on Peter´s PS board, it´s 22.000MF, M4 bolt terminal.
Thanks

Re: Re: Transistors
I did place an order. I didn't know that there was a difference with V, BL or GR? Did I just buy some junk? its not here yet so cannot confirm which type I have, but they are toshiba.

2SJ74 Datasheet :
http://www.datasheetcatalog.net/datasheets_pdf/2/S/J/7/2SJ74.shtml
IDSS classification make the grade difference
GR : -2.6 ~ -6.5 mA
BL : -6.0 ~ -12 mA
V : -10 ~ -20 mA

Having bought the Conrad heat sinks and waited the many, many months to get them, I'm now getting back to gathering parts for my very first F5.
Cviller, could you mark me down for: 2x F5 and 1x PS boards? (I would send a PM, but apparently I haven't posted enough to have PM privileges yet -- I've lurked and read for a couple years, though!).

advice??
trying to decide on power supply caps.between rifa/mundorf m-lytic's any advice or should i just stick with panasonics[I hear panasonic are light in the lowend!!]thanks peter

New ordersite
I have been brewing on a small site to help me manage the GB orders. I think doing these group buys is very fun, but copy pasting between my database/email and paypal has become a pain. Since I don't have very much profit on these board sales, I want to make sure that I don't have to spend too much time doing tedious work. 😉
Now you can order and pay online using paypal:
http://viller.eu/gb/
The site is very BETA like, but security should be fine (I rely on paypal for payment confirmations).
If you only want to test the site, you can do so until you enter the paypal site - here you'll have to pay or stop your test. 😀
The diode rectifier board available is 90x38 mm - I'll post a picture soon.

Shameless plug, but cviller said he did not mind.
There is still time to get in on a GB for Heatsinks and Optional Chassis kit. Configurations available for F5.
I am looking to wrap up the sign up portion of the GB in about 3 weeks.

I just got the package from MCM Electronics.
It says 2SK170 JP on the envelope and the markings on the device are "K170" (top row) and "BL 8D" (bottom row).
For the 2SJ74 it says 2SJ74 JP on the package and the markings on the device are "J74" (top row) and "BL 8G" (bottom row)
I assume these are the BL variety and good to use?
