ECHOPLEX EP-2 Schematic, please

[Олег Горшков]

I got ECHOPLEX serial number 9631 by chance. Hobbyists tried to repair it. I didn't find the diagram. It looks like EP-2. It has three tubes and the most unusual thing is four transistors.
If anyone can share the diagram I would be grateful.

Or maybe EP-3

One of the latest , hope it's in...

I don’t want to seem like an ungrateful person, but I have this entire album. As you can see, my English wants to be better. That’s why I wrote - the circuit should contain three lamps and four transistors. Resistors and capacitors of course. I appreciate your efforts with great gratitude.
