Hello all. I have recapped my vn900 about 2 years ago. And I was looking to replace some of the transistors on the amp boards. But I couldn’t find a good replacement for 2sc960/2sa607. So much just left it alone until now while playing relay started clicking on and off until it just never came back on, after further examination I discovered the two transistors went bad. So here I am trying to find a good replacement for them. Also I have read a lot abou a good replacement for the stv-3 bias diode. Does any one have a definite answer to a good replacement for it Is really unclear to me weather you can make one your self. Does any body have any experience making one ??
Your input is greatly appreciated

STV-3 - Replaced by three diodes connected in series. Epoxy resin for fastening.
STV-4H AND STV-3H diodes array
Install transistors in other cases, taking into account the pinout. Replacement can be clarified taking into account specific modes. Roughly BD139/140.

Hi. Thanks for the reply. I’ve tried 2n3440 and 2n5416 with good results. The 3 diodes(1n4148) in series and pow �� I took out one of the transistors and a 220 ohm resistor. Thankfully I have several replacements in stock. Is there an specific way to install the thre diodes. I have read slot about this home made diode but haven’t found l pictures.
Thank you so much in advance.
