Here's some photos of my Jet City JCA22H.
It's a very nice amp for very little money.
Does AC/DC well.
Wish it sounded more like a DF Pink Taco though (anyone have any mod suggestions?).

Re: Jet City JCA22H
Dave mods these amps and they sound really good.
Do you have a schematic? Folks might have some suggestions....

Re: Jet City JCA22H
Replacing caps in signal path with better quality (Sozo, Orange drops 716p, Wima FKP/MKP... ) improves the sound very much.
As far as I know it's ~20 watt SLO circuit. So it's SLO preamp with Atomic 16 / Astroverb power amp.
Put Lar/Mar PPIMV to push the El84 harder, and good caps will open this amp.
You can try to replace Metal Oxide resistor on B+ (HT) with a choke (3H 100mA if I remember) or Wire Wound resistor (less noise).
This is a very good amp, those simple mods can make this amp sing!
