Linear Systems Matched LSJ74/LSK170 JFET pairs (Grade B)

Otherwise everthing was/is great but I wish the JFETs would have their Idss specifed. As they have been matched anyway, why not write down the idss at the same time? This would be valuable information for the user.

Excellent parts!

I bought these parts for a souped up F5 running, what I intended to be, 32V rails, which actually proved to measure 34.5V rails, and was concerned that the J74 part wouldn't tolerate that kind of overvoltage well. As it turns out, the pair handles it like champs with a little bit of heat sink between them. They're excellent parts working very well beyond their technical specs and they sound excellent. VERY pleased with them.

These are great devices!

Looking forward to using them in the F6 unit I am currently aquiring parts to build.
