Hi,
I have previously sought assistance on my OTL3s. These are the very early versions. The issue then was with V1 which started to glow orange within minutes of switch on. Many possible causes were suggested. One that suggested that V1 was not as strong as V2 and V3 as these operate as one appears to be correct. I have finally manages to find a replacement 6LF6 that does not glow orange.
As soon as this issue was resolved,there is now a new issue, V5 now starts to glow orange within seconds of switch on. I suspect that these 2 issues are related although the circuit dia. seems to suggest otherwise. Ideas on possible causes and solutions would be much appreciated. I have checked all the caps and resistors, all are spot on or just marginally off.
In view of these 2 issues I have not been able to bias the amps. Thanks in advance for your comments.
Rgds,
Nara
