GB Thread for Salas SSLV1.1 BiB shunt reg - Page 98

Just maybe, without C/W data and ventilation of that ''box sink'' there is no scientific answer, but there is a rule of thumb, if you will measure more than 70C on the actual metal tab of any Mosfet its not long term reliable. Apply high quality thermal paste, it helps.

Then i can maybe sink one of the regulators at case bottom, and the other regulator gets its own sinks.
Will be pretty much stuff in the case, since it's a parafeed tube line-stage w. buffalo dac and i/v-stage in the same case.

Mike, i missed two 1R resistors in my IRF- set of components, no problem though, since i will still need to order a few parts for voltage-set part.

When this +-15v regulator will feed my I/V stage, would it be recommended using a 220u electrolytic instead of an 10uF film-cap for C101/C201? And is it better running 2x1,7v leds instead of a zener?

Just received the BiB boards and the minikits. However no DCB1 parts or board. Did you send these in a separate package Mike?

Tea-Bag · 22nd July 2012, 01:51 PM

Due to lack of boards, I have added a new sign up spreadheet to my signature.

pellesmil · 22nd July 2012, 02:34 PM

Safe and sound, received in Norway

Thanx

Just signed in... I added a column for the names

Mike I am measuring the green leds from the minikits at ~1,84V and the reds ar about 1,7V is that right? or am I doing something wrong? I expected something ~2,1V and 1,9
