I'll give that info a little time tonight, thanks you guys, I appreciate the interest and help! 

The math before me is like an irritating repellant before a garden-pillaging rodent. 😂

Ok, fair enough, I stand corrected.

Not necessarily. I'm still measuring the same way today as I did in the 1970's and every product I have designed uses power based on RMS metrics and states THD...

The guy who's been repairing my amps the last 6 or so years there me that measuring at 1KHz takes less power than lower frequencies, so the rated power brings a higher number. This is incorrect?

I toured a MkIV AH250 through a red stripe 4x10 back in the day. Wonderful amp although 20 years later I acquired the same model for nostalgic reasons and the sound wasn't how I remembered it.

I got into the SMX 12 band stuff with the tube and the dual-band compressor. That was my favourite preamp and I'm not sure if anybody has bettered it.

Power ratings are so unpredictable. I hear people complaining today that a relatively recent 300w Class D head is hitting it's limits. 300w seemed a lot in the 80s.

Power is measured differently than it used to be. The numbers get blown up and it seems like power just ain't what it used to be. It is, it's just sold "differently"... Advertising...

Here's the one covering the SMX. It also shows the GP7 (still Series 6 at this time) and some of the Valve series.

There's another brochure that came after this that covers the SM range along with the SMX range.  I'll sort that one tomorrow. 😉

 

 

I remember drooling over the SMX line in '95...

I never knew that Trace did a 2x18 cabinet.   Fantastic. Impractical but fantastic.

Old school dub reggae players could get with that I think.

Thanks everyone for posting. 😎👍

A rehearsal studio in Hertford used to have a Series 6 410 and a Series 6 112 combos  that sounded amazing. I think they were both rated as 150 watts without an extension cab. They were what brought me back to TE amps. I'm not one for mid cut pre shapes, but there's something about that original Trace Elliot pre shape button that just works so well.

I like the presentation and then bringing in some mids with the graphic.

Not really. The issue is that Trace power ratings are honest continuous RMS ratings so what a 250W Trace is rated at would be described as 1000W by less scrupulous manufacturers.

 

Bear in mind 2,500W is only twice as loud as 500W, other things being equal.

This about honest ratings hits the mark. My tech friend says similar about how power is now rated at 1k, which isn't really honest low end. It requires more power to reproduce low end, so you get higher, impressive numbers. 

Thank you guys. 

I've got a kind of prog-ish doom style original band, I play bass. I'm in process of getting a Mk IV head cleaned up and installed in a plywood sleeve I made, and I'm thinking about running it into an Ampeg PR410HLF cab, 600w @4 ohms. 

The Mk IV is rated at 250w, 4 ohms. In my experience, Trace heads seem to deliver more than that. I'm thinking this'll be loud as Godzilla with a stubbed toe in a mix with two loud guitars and big drums, playing some melodically complex bass lines.

Can I get witness?

First word back in the amp is that the power section seems stable. The big blue caps are in good shape, so far so good. 

My tech guy had to clean up the fan, it was lousy with hardened crud- but once he got it free up it was working just fine. 

The preamp is next...

And the sleeve is looking ok. I'm bringing it to the big panel saw to do a cut-back on the front panel section- like you see in a lot of these sleeves- so you can see the uv lit front panel from above. Then I'll rattle-can it with some black forest green and finish it up with some old hardware I've got in a box, somewhere around here...

So I've got the amp at the shop, dude's taking his time because I was clear I'm not in a hurry, all's well.

I'm getting the sleeve shaped up, but I neglected to get the dimensions of the casing for the UV light. Anyone happen to know how high that dimension is? I want to do a back-cut at the front, as you might see in the later models... And so I can see the controls (the reason for it I guess) when it's sitting on a half-stack, single cabinet. 

It won't be exactly to spec, but it'll do the thing. I just want to do the cut without exposing the end of the UV case...

Thanks. 🙂

Oh, god.  The valve window.  No doubt with an LED behind it.  Marketing bollox.

Tacky, cheese, yes. But Kustom's web site says it's active in the gain stage.
