Shootout of the JCA's!
Clip starts with the JCA100H modded by Zach at titan amps to have the SLO internal circuitry + KT66 power tubes.
Second amp is another 100H with both the internal SLO mods as well as an O'Netics output transformer favored by all the guys that build SLO clones. Same brand KT66 power tubes.
Lastly is the bone stock JCA 22H just for fun
Volume on the tracks has been leveled but it's worth mentioning that with all 3 amps with their EQ's set identical and volume knobs set identical, the one with the O'netics transformer was about 5.2 dB's louder than the other 2.
