Got 2 beta 87 mics one wired, other radio head both have broken transistors in them, the wired version had a 2SK377 & the Radio mic head had a 2SK170 (surface mount tran if i remember correct)
question is are the 2 FETs basically the same ??
Where can I buy them from UK ??
Cant seem to find here in UK apart from evilbay, wondering if there is equivalent to look for ??
Ive read of a few mic mods here and the 2SK170BL comes upa lot is the BL version a low noise & better option ?
Also want a 2SK170BL to build a Octava type mic circuit
As a desperate measure I tried a FET found in a electret mic from a cheap old cassette recorder I had laying around, to my suprise it works & seems to work ok , I cant A&B it to original maybe it what be noisier so would like to find correct or ugraded FETs
Ant advice would be great, thanks for reading.
