Does the 100 watt amp really use 6L6G tubes? Or are they 6L6GC tubes?
A shopper
on Aug 12, 2023
BEST ANSWER: G means glass case. -GC is what 99.9999999% of tube amps calling for 6l6's call for.
Found succinct explanation for TDPRI user clintj:
6 - 6V heater filament.
L - denotes the particular tube within the 6*6 series
6 - 6 elements including the heater
G - glass envelope (vs metal)
C - revision of the tube.

i wonder if this will fix the issues with the first amp? hopefully the drive channel is louder and there’s a better spring reverb. id love to hear thoughts on anyone who can compare the two

Tube clarification question: The specs say this has four preamp tubes, but there are clearly five in the photo. Three preamp, one reverb, one phase inverter? Description says two 6L6 power tubes, clearly 4 in the photo. Other differences from the 50-watt head seem to be: a larger power transformer, 4-Ohm output (so a different output transformer), presence control, metal corners. Looks like the same short reverb tank.

SB100 100-watt. I wish these Q&A sections where specific to the actual product. I don't want to read about a combo amp or other variations. I want to read about this head for thoughts on it.
Why is there not one VIDEO posted on Social Media for this new head? It's the big brother to the 50watt unit I would think you would want people to hear what the differences are. When will some actual play-through be put up? I'm not considering a purchase until I see that?

Very clean,doesn't break up. The quietest tube amp I've owned I'm using a power soak sounds good in both channels. Thickens tube sound.Monoprice people are great with all issues and warrenties.
