TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.Not that good. You asked for Pentode/Triode and I gave you UL/Triode.

TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.You could take the Ground switch out and replace it with a UL/Triode switch.

TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.You need to draw load lines to determine this. The highlights are at the intersection of the 0V grid curve and the class B load line...

TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.Whereas my schematic has a different overall appearance, the circuit contained therein is exactly the same as the Fender schematic. The...

TTen Over replied to the thread '68 Bassman, blew Tally light, weird resistors?.There are advocates for the artificial center tap on the grounds that the resistors will burn-up in the event that a power tube shorts...

TTen Over replied to the thread '68 Bassman, blew Tally light, weird resistors?.Then I would think that the real center tap in the picture is taped-off inside that heat shrink. If you really wanted to be certain...

TTen Over replied to the thread '68 Bassman, blew Tally light, weird resistors?.Now that I have looked at the pictures, I have changed my position. It appears as though this heater winding may have a real center tap...

TTen Over replied to the thread '68 Bassman, blew Tally light, weird resistors?.Tally light? You said that it has 100 Ohm resistors to ground. That constitutes continuity, doesn't it? I'll bet the ohmmeter doesn't...

TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.Maybe you should try connecting the 6L6GC's in triode mode. That'll drain the testosterone right out of it and give you one of the...

TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.I don't understand this, but KT66 will use 1.5A more in heater current than 6L6GC. Will your PT willfully supply this? Also, KT66's...

TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.It's the change in the circuit with the 135W that puts 280V on the PI plates, not higher supply voltages.
-
TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.The AB763 Twin Reverb has +410V for the pre-amp supply and +450V for the PI supply. The 135W Twin Reverb has +365V for the pre-amp...

TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.No it isn't. It is being used as a bridge rectifier. Removing the centre tap will have no effect on the DC voltage. Connecting the...

TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.Hammond has the UL tap at 20% on their replacement 135W OT, if anyone is interested.

TTen Over replied to the thread Remove Ultraliner OT taps - quick glance.The idle current is already low with the stock bias circuit and typical 6L6GC's. Reducing it some more doesn't seem reasonable to me...
