Hi Patrick, just beeing patient and keeping a very keen eye out.

Just a query - on post #64 back in Feb, you mentioned that you were using the "Standard DAO" at 195mA - Is this the previous non-Taylored version with the IRFP fets or is this pushing the smaller 2sk/j units well above the 100mA detailed in the design sheets?

The 2SK2013 is a TO220 device and fully capable of 200mA or more in Class A.
The very original schematics I published years ago uses a 2SK1529 at ~330mA bias.

Time to publish Part 4 & 5.
Next on the to do list is to test the new TCS circuit.
Needs to get new PCBs made first.

Like all of us, this is hobby for me and I happen to have a busy day-time job as well.
Hope it is understandable.
