Hey Everyone... I bought a cash of these RCA 5963 tubes.. told that they are very very similar to 12AU7 tubes but draw more current.
With the DIY70 board can it (the driver board) support this tube without changes?
"5963
This tube makes a decent substitute for the 12AU7 as the characteristics are almost the same. The 5963 has a slightly lower plate voltage rating compared to regular 12AU7. The 5963 has a max plate voltage of 250V while 12AU7 has a max of 330V. This tube has a specially designed cathode which can withstand long periods of time in cut-off without hurting the tube. "
