Ah, that’s right, I forgot that part. I recall discussions that some owners bought the upgrade just for that, as there were some mixed feelings about the compressor. I also recall a conversation with David where he mentioned that the upgrade included some enhancement of RF resistance in the front end - sorry to be vague, I’m not a tech.

Is David still around?

I expect but don’t know. @Rip Van Dan would likely know his status. There are a few other Eden threads you could look for as well.

Yes, he is around. He is older than me though and I'm 73. He had to close down DNA this year because some of the proprietary parts he uses are no longer made for either his amps or his speakers. The companies that made them went out of business in 2021 due to Covid. But yes he is still around. We traded e-mails a few weeks ago.

I had to check both the WT500 and the WT800 because that amp I have was the one that David used to design Eden cabs from 1999 until he left in 2009. It's actually a WT500 that he upgraded with the WT800a power section. I usually refer to it as the WT500/800. He signed it for me and initialed the upgraded power.

Yes I can, as I had one just like it. It was mid-nineties I believe, and it started out as a WT300. David Nordschow then offered the option of an upgrade to the new 400w power section. It wasn’t a huge difference, but he also threw in an upgraded DI, fan and a couple other goodies. I gigged that amp for many years and I hope you enjoy it as much as I did.

Hello again.
I contacted someone at Eden and they said because the back of it says 260 watts so it’s not 400watts. Could this be true? How can I know for sure?

As I think about it, my amp said “300” on the front panel, and the back was changed to “400” and dated by David. That makes yours a bit of a mystery as it says “400” on its face. I got nothin’ more for ya, except to say good luck. You got a classic, enjoy it. Those amps are plenty loud, no matter what it says on the case!

I hope there’s someone who can chime in and let me know. It sounds great but still want to know what I actually have

Hello Tom
Can you show a picture of the inside of your 400?

As I recall, the original Eden World Tour amps all use the same PM400 power amplifier modules. Thus, the difference in output between models is due to beefier power supplies, with higher capacity transformers, higher voltages, and increased supply capacitance. So, a WT-400 probably doesn't look much different inside than a WT-300, except perhaps a bigger transformer, and maybe larger supply capacitors. Also, the WT-400 has a pull-pot on the input to disable the compressor. If it says WT-400 on the front panel, chances are that's correct, 400W into 4Ω.

It does have the pull pot on the enhancer pot to bypass compressor but not on the input pot.It’s somewhat visible in my picture.
