PTFE 4P socket for 304TH/TL 10,000yen

304TH/304TL is very large Triode output tubes that were manufactured with EIMAC etc. Although there is not an external form so largely the heater capacity is extremely big 125W. It is the large tube that even the plate dissipation reaches 300W. It will be able to call it with the vacuum tube that adopts the tungsten filament and enclosed extremely big capacity into a comparatively small appearance. The capacity has the capacity that endures famous WE212 as an ultra large tube. Moreover, this vacuum tube is done when it is comparatively handy because it has a reasonable amplification rate and plate impedance for the audio device. There are many such voices that are not able to use it because there is not a socket even this vacuum tube and produced and designed the socket to the exclusive use in our company.

The PTFE that prides in the heatproof nature of about 250 degrees, after the adoption, neighbour bronze the body did the plating of the high strength foundation of the unmagnetism to the pin firmly the gold plating of the rather thick was performed. We are making the hole for the ventilation a lot to raise the radiation production to the body.

As for 304TH/TL the capacity of the heater circuit is big, we considered it so that establish the ventilation mouth to the pin department and let go the heat as much as possible because there is much generation. In the case that it is produced the amplifier actually we are careful of the radiation and also ventilation and please design.
