Got the packet yesterday. Tested today . All are original, good, NOS only. But have some rust and dust due to long storage period. But bottom side is clean. Have a look. Within 2-3 days I will measure the pinch off voltage.

Graded the VFETs and got good/decent pairs between same sex. Good for connecting in parallel or for repairing Sony VFET amps. They are not cross matched between N and P. Very difficult and not required. But selected best possible pairs between N and p.

All of you, who purchased, got PM about shipping details

Yes, a TA-4650 with all R57 ratings. Just got it and tested the devices, need to check the power supply today to confirm general functionality before purchasing VFETs. The 60s read 0.8 ohms across S to D; one is 032 in diode mode across S to G and G to D; the other, 075. Thanks!
