Used Peavey JSX Mini Colossal

[Catmandue]

I spotted one of these which I picked up today. It is suppose to be 5 watts. It has an 4/8/16 ohm select switch. It has a built in adjustable power sponge. It comes with an 8 ohm speaker 8 inch speaker. When I measured it was around 7.8 ohm. It has a good tone. It also has a built in tremolo with speed and depth adjustment. The only strange thing about it is the tubes are located in an odd position, with a hard to screw back on cage. It has one 12AX7 and a EL84, both are JJ Electronics. I only had it plugged in briefly, I will probably put a Jensen P8R in it. I may change out the tubes to Mullard for preamp and TAD for the power tube. Here are some quick shots I took. Sorry about the quality. I was in a hurry doing five things at once as usual.

That looks neat. So, you can unplug the speaker, and then run a cab of your choice with the speaker selection. Cool.

I want one of these! Sadly they are very rare in Australia. Even the full-size JSX models did not sell a lot of units.

This would probably sound great through one of those closed back Orange PPC112 cabs with the V30 in it.

Very cool little amp. I bet it has a big sound

It will after I throw a Jensen P8R at 4 ohms in it. While in there I'll swap out the OEM? JJs. I can also run it through a WGS 12 inch 16 ohm Green Beret.

I'm pretty sure that on these tube amps with the ohms selector switch it doesn't make any difference what the ohms load is as long as the switch matches the load. The switch effectively adds a dummy load so that the amp always sees 16 ohms.

If the ohms load is too low then you'd arch the tube socket and destroy the EL84

The switch usually selects the correct tap on the output transformer, it does not switch in a dummy load. You have to be sure to select the correct setting for the impedance of the speaker you are using.

The speaker reads 7.8 ohms so I'm safe running switch at 8 ohms. I just gave the little combo a try again just now and played for about an hour on it. I used an G&L asat tribute, Morning Glory V4, Sunface NKT Red Dot, Morley MTG2 mini GL Dragon 2 wah. The speaker is nice and broke in. It has a mellow warm tone. I want to try an SG Special through it, with the same above mentioned gizmos. The speaker sounds good but I'm changing it out along with the tubes. I can always swap back if I don't like it.

The power soak keeps "your" sweet spot even at lower levels. It actually works like it suppose to.

I was waiting for you to chime in cuz! I like a couple of Peavey tube amps. Peavey makes cool stuff. I like their guitar too.

Yep -- Im a Fan of Peavey Gear -- and TBTH I never heard of that one before !!! I am all JELLY ous

Years back I had a Peav Bass with a 3 band active eq, and when you hit that switch that boom stick came alive...I wish I would never have gotten rid of that one..

Its was in between Candy Cherry n Maroon...What a BOOM STICK

 

[Catmandue]

I put in the P8R to some very nice results. I also put a Tung Sol 12AX7 in it.
