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 |
