RE: NYAL OTL3

I just read your entire thread, just because you purchased a dozen tubes thru ebay that doesn't guarantee a fix, the tubes need to be tested for plate current, if the tubes are not matched you can do more harm than good, by switching the tube around you should be able to find a configuration that they will align properly. If you cannot get 300ma idle current when going thru the alignment procedure then they are all probably weak tubes. If the current takes off well over 350ma within a few seconds of powering up then you need to start replacing the Zener diodes until you get a smooth rise in current hopfully around 150ma with screen controls at the lowest setting, this will give you plenty of range to align them properly.
If you don't have the alignment procedure let me know, seems like I have already sent it to you.
