labjr. Mr. Pass may separately A/B compare the performance of his F6 with the Old Classic. He may use the Delco design in post#1085 which is well detailed. Otherwise, will he and us ever learn whether F6 is an improvement? Was there a performance comparison between JLH and PLH?

fact - Mr. Pass pre-published some things from article which is going to be published

as many times before - his article will show it's purpose



be sure that our Japanese (and other , from Far East) friends will buy original F6 , without asking too much about comparisons

they'll hear it , or hear rumors , and they'll going to pay

Quite an interesting [non-technical] analysis. The success of F6 may even spur DIYers and competitors of Mr. Pass to rejuvenate the Old Classic design itself with state of the art bjts and passives in Class A and AB flavours.

it's already happening ;

anyway , we mostly don't have enough insight in things happening on East

all we are used is to brag how they're cloning things ....... but nada - Japan and China are more technically similar than we can imagine and they ........... naah ........ that's story too long to even mention , let alone start , in form of Off Topic in any thread .....

Default Two PCBs available.

I have ordered prototype PC boards. There are two boards that are not spoken for that I am offering at my cost of about $30 US per board plus shipping. I expect to receive the boards on Sept. 7.
