Dear Apex,
Thank you so much for your fast response..
Are there any sound changes referring to this change by using 4,7 uf instead of 10uf? Because it means that the new one is less than 50% comparing to the previous value.
Many thanks.
Best regards,
Arif

New to this thread and would like to start at square 1 with SR50 but can't get BF420/421. Any suggestions for direct replacement (ZTX457??). See these were dropped in versions of SR100/SR200. Thanks

Thanks for the quick reply. Unfortunately, the recommended replacements are even harder to source here ie BF471;s/871's! Can you suggest new alternates or a supplier? Maybe I should skip the SR50 and move to SR100...but I would like to start slowly,

MPSA42/92 can be use, but pins are E-B-C instead E-C-B (BF420/421)

Dear Mr. Mile,
I am sorry for giving you this question...
What is the best bias setting for SR200 when I measure across r10Ohm (temporary replacing the fuse)?...I read this bias setting before but I forget the value...
Best regards,
Arif
