Dear Mighty ZM,

A silly question: Am I correct that if I want to use Cinemags with your pcbs
then one would need to cut off pins 1,6,7,12 (the same way as with SissySIT)?

Thanks,
Dennis

almost forgot to reply ....

yes , I believe so that you need to cut 4 outer/corner pins

though - it'll show itself when you try to align them on pcb

if needed , post few nice pictures with Cinemag on pcb and I'll explain what's necessary

in fact , considering that those pins are NC anyway , nothing wrong if you cut them without much thinking

Hi Mighty ZM,

For the input buffer jfets, would higher Idss be preferable (say 10mA vs 6mA in
the BL range)?

Also, how high/low value for the pot is recommended? 100k Alps is available
at mouser and I think 20K and 50K at other stores.

Thanks,
Dennis

higher Idss is OK , just keep an eye od dissipation (say no more than 150mW per JFet, more is making me nervous...if needed ,just increase resistance of source trimpot,, meaning - use first bigger value )

pot value - that's relevant to sources you have in front of pot - more cojones,lower pot value

so ,10Klog to 100K log

Some progress has been made with most of the parts stuffed.
I've also found and picked out jfets for the buffer. For the transformer,
I'll likely use Cinemag (low nickel).

For the 14 pin header, is there a recommended part? The pitch seems
to be 2.5mm or 2.54mm. Would something like these be suitable?

Thanks,
