Went to the post office to collect the 2 pairs of RCA 834 tubes. While collecting the B4 sockets for the Telefunken RGN1064 from Joh, he mentioned that the top pins would need to be "heat sinked" in order to dissipate the heat otherwise the glass would crack. One of his friends encountered this issue with a similar tube. I remembered coming across a site somewhere on the web where a DIY guy can help machine those top caps meant for the 833 tube. Need to do some searching...

Anyway... this will be a build that I'd attempt only after I managed the RCA 808, which has been in the pipeline for a long time. I need to finish up the 1626 first (some adjustments need to be done on the aluminum plate so that the top plate can be accommodated. need to get a few short standoffs as well), then build the Sabre32 DAC with Broskie Cathode Follower with a Salas High Voltage Shunt regulator, before the 808 project starts.

Have been collecting the 808 tubes on and off for a while. Wanted to build the Shishido 808 amplifier with the inverted interstage design. Most of the parts are here, just lacking of the power transformers. It's really a long term project. Something that I can slowly enjoy the build process with.

Anyways, here's some pics of the tubes. Anyone with spares to sell can contact me.
