This store sells them with the hfe that you decide.If you can find one, sure. You'll pay a premium for that particular part number and there are no guarantees regarding leakage. I would suggest finding another device to save some money unless you're very set on it.
Position 2 (4n7) is the 'stock' position. Keep in mind that it's a rotary switch, so you may have to test it to see which position is actually being connected.
Hi everyone, I wanna build this Range Booster but I not sure about the transistor.
One OC75 with 75-100 hfe will be a good option?
Also I don´t know wich mode is on the eight positions of the RangeFinder.
Thanks for help
I'm from spain that's why I'm looking retroamplis, I think I Will buy It with hfe 75-100.You’ll probably have to tweak the bias arrangement of the stock circuit to accommodate the leakage of the OC75.
Having ordered OC75 from Retroamplis I can vouch for the quality but keep in. I do that thier prices are in Euros so be prepared to pay $13-$14 each.
Try Small Bear for a RM specific device. Then you know it’s tested for that circuit.

Some recomendation for biasing? Thanks.
