HI everyone, new Aussie member here, how are we all, rockin the sunshine? Great forum you have here!

So i picked up one of these little box's and waiting for it to arrive in the mail, so through research i stumbled upon this thread. I have a question if its ok, i'm pretty limited on tube based knowledge, i know a little though that voltage stuff is all new to me.

Can anyone describe in lamens terms what you are talking about when it comes to the 9V/300V subject? Not sure what any of this means really but would love to learn:) If you have the time feel free to school this grasshopper. Is it another option you can switch to, the general idea behind the pedal and tone wise, what is the score?

Sorry, i am very curious, looking forward to plugging into the Spider-valve MK1 HD-100 for a little warmth, also grabbed the AMT EQ7 while i were there, good times comming in the post right now,

I'm not sure I understand your question, and I'm guessing that's why you haven't had a reply.
The Tube Magnum runs on 9 volts, but it bumps that up internally to around 300 volts as part of it's design and normal operation.
There's nothing to switch... just plug in and crank it up.

It's a fairly complex design so I suggest you don't "go in" without a plan.

Hi

Thankyou for replying.

I must have read too far into an above comment, i am always digging to understand my gear, prob too much but im just interested plus it helps when tweaking the box to know how it works, for me anyhow

Very keen to give it a shot, i have tried a few AMT pedals and they are not half bad I have the EQ7 comming too so i can run it in a loop and shape if needed, gotta give it the full test run i guess

Again thanks for the reply

This pedal like many others uses an internal voltage on the plate of the valve, the internal SMPS circuit giving out apprx 300v from a 9v AC power in. SMPS=Switched Mode Power Supply. Do a google search for "Nixie PSU schematic" and that will show you a psu schematic for the 9v to 300v step up PSU.

Tonetweaker, could you re-post your pics?
