I did it, really simple with just a screwdriver. Your going to have to pull the chassis out though.
Biggest thing to remember is you'll see the unfinished inside of the headshell through the metal grill.
I'd tolex that part, or paint it. Anything to just make it look black.
You should check out NAM (neural amp modeler). It's complete freeware open source. It's similar to the tech in tonex or the Kemper. There's a massive community dedicated to capturing all sorts of kickass gear and posting it for free.
I have a current helix and NAM kicks it to the curb. Only...
You could plug the speaker out directly into the PS as well. Don't even have to turn on the poweramp. Run the PS line out into your DAW or whatever and just add a free VST IR loader to your signal chain.
There are so many great free IRs out there it's a non issue.
From there the PS let's you...
You can always take the line out from the power station into a DAW with a VST IR loader for recording.
Having a poweramp for random shit is a huge + in my opinion. I use it for a W/D setup sometimes and it works great.
Bogner 101B w/EL-34. I've yet to find anything equal to the blue channel. Great super reverb clean and a good higher gain channel as icing on the cake. I'd probably still pick it if it was only the blue channel with a boost honestly.
Goldfinger SL is a close runner up.
Sometimes when I'm in a rut I go to the factory preset bank and just play and scroll. So many unique sounds that can inspire creativity. The "harmadillo" is my latest favorite. You can get some cool syncopated rhythms going with the various filters you can tweak.
I just shipped a 101B back to the mothership in LA. Fully insured was 133 bucks from Hawaii through pirateship. That was 60 bucks cheaper than the UPS store quoted me. Don't know how they do it but I'm a fan.
Just get a H9, preferably used if you're trying to save some $. It can do a lot more, but it can do excellent reverb in about any style you'd imagine in typical eventide quality.
You should try a Goldfinger SL. Does 60s/70s/80s like the Helios, but has a clean channel that's easily bogners best (and foot switchable). Add a tailorable boost for each channel and it's my favorite of his designs
