I arranged parts. I finished producing.

The voltage necessary for the vacuum tube did not go out, and the sound was not emitted.


The pattern was chased, and parts were checked.
The AC adaptor is not CISCO. No be known probably because of that.
CISCO's adaptor is obtained now.

Obtaining the case and Japan's heat sink is difficult.

The stopping and case are being produced using alternative parts such as TAKACHI.
It worries about whether it goes well because it is CISCO 48V200mA though the AC adaptor was ordered yesterday.

Do 10kΩ and A curve Pot (LOG)?
As for the ALPHA product, because obtaining is difficult, substitution Pot is scheduled to be used.
It is expensive though can easily obtain if Diji-Key is used when thinking about the exchange rate.

OK Thanks,
When it is Japan, it is hard-to-find.

I find that an easier way to separate the two parts of the tube socket is to drill from the bottom slightly off-center. This should weaken the flange on the bottom part of the pin, which you can then easily tear off with pliers.

I spent the whole night tonight trying to separate the socket without a drill because i don't have one, and I broke two of them already, and a screw driver. The socket is just unbelievably brittle.

Yep - sorry to hear it, but that's why I drill mine. Some people are able to do the screwdriver thing without a problem. I don't know how, though.

Maybe you just sent me two really good sockets


I started with a spudger (plastic tool used for opening electronics cases without damaging them) and switched to a small flat head once they were opened up a bit. I definitely don't recommend trying it this way (as apparently very few people have had success) but if you're desperate I can confirm that it's possible.

May be the ones I've received are different. The whole socket cracked after I try to pry them apart.

And the ridiculous thing is, after the socket has cracked, I am left with just the pin. I hold the two sides of the pin with two pliers and try to pull them apart. They just refuse to separate... I am not a super strong muscular guy but I am still almost 6-2 and not THAT weak...


I don't know what to do now. I broke two and I still have two left. I feel unethical to "borrow" a drill for one time use for this, but on the other hand I don't think I have a choice, since Tom doesn't have the time to drill it for me before he sent it out because he has such a lot of order to handle.
