The layout is very simile to 2A3 but one of the pins a few mm away, far enough for me to consider that it would not be save to bend the pins. So, what I heard is that in 30-40 Germans made the similar pins and I wonder if any tubes sockets for them are available? I told that there is a Germany aftermarket company that make those add sockets very recently. So, since you are in Germany, or any other Germans – did anybody see the “faulty” not-fitting 2A3 tube sockets? It is not imposable to accommodate some other solution to YO186 but I would prefer to buy off the shelf socket and do not be bothered with it. |

Ok, it looks like the YO186’s tube sockets are not the problem at all. The experienced James Gross from http://www.vacuumtubesinc.com listened me about the YO186 pins and proposed to use old British 5 pin socket, and just do not use the mid pin. British had zillion names for this socket: 4pin- A, A4A, B4 and 5 pin- DA30 ML6 U20 U18/20 B4 B5 X4. It looks as it was wildly used with such tubes as DA30, HL2, KT2, KT21, KT24, L2, ML4, ML6, MU12/14, MU2, P2, PA1, PA20, PA40, PM2, PX4, PX25, RE134, RE144, REN804, U10, U12/14, U16, U17, U18, U20, U21, UU4, UU5 etc.
I never used any of them but it is not a big deal to found them, even Chinese nowadays make a tone of them, the “gold” plated.
