Wanted qty-4 TH562 / SD1731 PA Transistors
"Graham" Wanted qty-4 TH562 / SD1731 PA Transistors ** FYI to readers: these are obsolete "strip line" RF transistors made by " ST " for use in SSB, linear amplifiers up to 30MHz ( ie the HF band). Any ideas as to supply of 'genuine' items ? The OP knows there are offers from on-line dealers in HK & China at about US$ 85 a piece. But he has nagging doubts ... I would too. ..... Phil |
