Can anyone suggest the "best" 300B SE sound quality schematic for a beginner like me?

hi,

I prepare ths to newbie diyers, very cheap price that every diyers can affordable.

this is the OPT of the kit,
circuit was same as the 417A/6c45 to 300B but EC52 had larger plate resistance than 417a, so I cannot ise IT, if USE IT I must use feedback. so I back to use 0.22 uf couple to 300B.

OPT was double c-core 19H 102ohm.

band width from 23Hz~45Khz -2db


thx

thomas
