Is it possible to make your own 2SA798 transistors out of 2 other transistors? I just looked and 2SA798 transistors are priced at $30 plus each!!!😀

I use a matched pair of 2N4403s glued together using thermal adhesive.
Very successful as they track perfectly with temperature changes.

Yay! That's what I wanted to hear! Thanks, Jon, Ill hunt some down and do that. 😀
If you clamp them together ident to ident, (the flat front) hook one emitter wire around the other to produce a single wire for connecting. I like the 2N4403 because I don't have to worry about the pin out as it is printed on the front of the transistor. (Must be an age thing).
Make a note of the pin outs before tie wrapping and gluing them together.
I use TBS20S | Electrolube Epoxy Thermal Adhesive, 48 h Cure, 20 ml Syringe | RS Components
I am sure you will be able to source a similar product.

My local electronics shop only has PN200 to substitute for 2N4403. I wonder if they will do? They are T0-92, 45vce, IC 500ma, HFE Min/Max 80/600.
Sound good to me. Try and select the highest gain you can get.
We are looking for 250 or more
