Jet City 22H comes today

[Reckless Abandon]

I actually found my SLO clone to work well with a T75 when i was using the BKP aftermath as the SLO has a bucketload of mids and so did the pickup. So the relaxed mids of the T75 worked out very nicely indeed

Yea right now I am really enjoying it with the T75. Buy since I've never had an SLO type amp I am wondering if I could get closer to "that sound". Of course I do not know what that is LOL. Thanks for all the suggestions. I will keep playing and listening. My wife just informed me w are driving to Lexington. The only good thing is a GC is there. So I will try some stuff if possible.

Thanks.

I guess I am thinking thick and warm but still will cut for solos and not be too booming on palm mutes. My jcm800 combo rattles so much. I think I need a cab too.

Ok bought a used Jet City JCA 12S cab.
Sounded real round and warm to my ears but with plenty of thump. Tried it with the single channel JCA 20H. A lot warmer than what I got at home but still let the high end come through.

Isn't the Eminence headquarters in Lexington or very near there? You're right near the belly of the beast so to speak.

Hour and maybe 20 minutes away fron LEX. I am actually 2 hours even further away. I live north east of Lexington on the Ohio.

I had some JJ tubes lying around. Put the power tubes and v1 and v2 in. Not sure I liked the result. Warmed it up which was good but seems the low end is not as heavy and pinch harmonics are tougher to get.
Now these tubes may be a little "tired". I had taken out of another amp and out news ones in for some reason. Going to put stock tubes back in tomorrow.

Re: Jet City 22H comes today

Try a Tung-Sol in V1 and Chinese or long-plate JJ in V2. That ought to help the crunch channel at least. JJ ECC83s and that amp do not get along, in my experience.

 

[Reckless Abandon]

hearing that. What about JJ EL84's? Where I changed them all at once it sure if they were a good choice.

Al least they were lying around and I did my just buy them.

Re: Jet City 22H comes today

I put JJ EL84s in my JCA20H, and they work fine. I guess they're better than the stock tubes, but I think they came into their own once I biased them properly. Make sure you do that, if you didn't.

I'm not familiar with your level of technical expertise, but this may help you do it yourself in case you're not sure.

I'm afraid to mess with amp guts. Guitar electronics easy but other than changing tubes I do no touch em.

I think the power tubes were old. They were at least used a lot. The JJ marking wee almost gone on one of them.

I'm good on speaker, bought the jet city cab. Pretty happy with it. The speaker is based on an eminence v128

Re: Jet City 22H comes today

Interesting. I wasn't all that thrilled with the Jet City cab. I thought it lost quite a bit of high-end detail. That being said, when I EQ it for an overdriven tone, I drop the presence to about 3. So maybe it's just me. Clean, I go for about 7, though.

Compared to my 75 watt celestion I am real happy. Now the celestion was not bad either. If it was in a closed back cabinet it would be better. But for me it sounds good. May look at another cab in the future for the celestion or even something else.

jet city el84's have to be biased, ya kidding me? most el84 arnt

Re: Jet City 22H comes today

Congrats on your new 22H! I've had my setup for about 6 months now and am loving it. It went with 2 of the 12S cabs which adds quite a bit of volume and just fills the room better, but running just one is a nice change sometimes, maybe less acoustically confusing. Adding a Tungsol into V1 and V2 gave me a lot more clean headroom in the crunch channel which makes it all the more sensitive and sweet as you ease the level up to the point where it just breaks up. It can be quite sensitive looking for the sweet spot and is also a good tool for learning to control velocity, at least with my Les Paul. Just a HAIR more pressure on the string(s) will push it over from clean to crunch. The clean isn't exceptional but it's pretty good. I think you're going to enjoy the amp -Rod-

Re: Jet City 22H comes today

Talked to JCA on a email he said ,No rebias necessary, the 20 watt amps are fixed bias.
The amps do come with a variable resistor for fine adjustment if desired.

I think the term fixed-bias is the worst term in the amplifier world, because it's so misleading. It means that the bias does not change with the signal. Cathode-biased power sections use negative feedback to bias the tube properly with changes in the signal.

Fixed bias does not mean it's not adjustable. When you come across an amp like that--and I believe Mesa Boogies are the canonical example--it will be referred to as non-adjustable fixed bias. The Jet City amps are adjustable fixed-bias. See why I hate the term?

Anyways, my experience with biasing the Jet City is it really adjusted how fat or thin the response was, everything else being equal. I think mine are running a bit hot, just over the 70% plate dissipation level, but I haven't checked in probably a year. Maybe it's time to do that again. Anyways, it's there to be adjusted if you feel like it, although it's not strictly necessary, I guess.
