Thanks for all the helpful replies!

I think I will go for the K1068/J162. As Karl writes, I need to drill the heatsink but that shouldn't be that difficult:-)


Thanks again

Regards
Joakim

Hi,
When you power the amp up, use a bulb in series with the mains to limit any current in case there is a problem.
Good luck

Better make that K1058/J162. 2SK1068 is a JFET, quite different from 1058 and not at all useful in this application

Hehe, thanks :-) I did mean the K1058, not the 1068. Spelling error

Hi,

We still have some original FET'S used but okee; and the replacements.
Take care only to use THE SAME TYPE in a channel.

hi not too sure how you have got on with your MOSFET problem do not use these forums much. 2SK227 2SJ83 early Hitachi devices k denotes N=k P=j spares H-pak package device electrically same as 2sk 2sk in To3 package 2sj50 2sk135 etc but have some used but workers here from DVT500s which were a very bad "Ground shifter" similar to Crowns grounded bridge bought some many years ago just to strip. even if they worked it was all they were good for that bad!!!! my e-mail charlieb999@live.co.uk DVT 250s nice amps proper old school had some nice in bridge got some 300s here now 1 dvt 500s of no use apart from outputs
