I do not see the reference to what the original “issues” were. Very difficult to answer without that information.

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.

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.

What features of the SB100 are controlled / influenced by the 12AT7 preamp Tube?

I purchased the SB-100 in April 2024 and absolutely love it. It now has 250-300 hrs on it. After about 50hrs it really settled in to its sound. My question is are schematics available so I can compare it to other 100 watt heads on the market? Heads react differently to pedals and I’d like to be able to get an idea by comparing to similar designs. Thanks

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?

I have a Marshall 50 watt head. It's not a true tube amp but has a great sound. The Monoprice amp sounds amazing. I'm very satisfied with my purchase and am finding different tones every time I play.

Great value for the price
Bought this on sale for a price that I just couldn't refuse. I was considering building an amp, but just the tubes and transformers would have cost more than this entire amp. I understand there may be some variability in the supplied tubes, but mine are JJ brand 6L6GC and 12AX7/12AT7.
My 17-year-old has been playing it almost every day for two months, mostly at high volume, and it sounds great. Though not ideal, we're running it into a single 15" cab with a James B. Lansing speaker. With an EQ pedal, he gets the sound he wants.
I wish I could find a schematic for this amp, but so far, no luck. Regardless, if they're all as good as the one I have, I would happily recommend it.

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.
