Welcome! Need support, you got it. Or share your ideas and experiences.
I'm putting together the kit and the first set of tubes have damaged the FET (shorted pins on the JJ EL34). All the voltages check out fine.
The guys at Elekit-Japan have advised to change Q3 (left channel hum). Problem is I can't find the OEM part NDF02N60Z. A similar part number NDD02N60Z is available.
I was wondering if somebody can help advise if this is ok to replace with. The difference between the two seems to be
NDF vs. NDD:
- Package type (TO-220 vs TO-251)
- Continuous Drain Current 2.4 vs. 2.2
- Continuous Drain Current (Ta=100deg C) 1.6 vs. 1.42
- Pulsed Drain Current@10v 10 vs. 9
- Power Dissipation 24 vs. 57
All other params are same. Any help would be highly appreciated.

So the FETs Q3 & Q5 were replaced with 4a mp versions NDF04N60Z.
The little bugger is singing.
Thanks Victor. Problem is I can't get it here in India.
NDF02N60Z is only 50 cents each...
