Magnatone Revisited

[Blackburn]

Well I'm ashamed to admit that today was the day I first heard the famous Mag vibrato from a 440. I immediately looked up the schem and am still making heads or tails of it because I'd love to incorporate that 6eu7 circuit into something.

However, I also stumbled across a new site that is advertising brand new Mags with vibrato and all. Anyone know about these?? I just downloaded the price guide and man are these things up there with all the other booteek stuff. It is good to see these things being produced again and hopefully they'll sound good... They better for what's being charged!

Check it out and let me know if you've heard one.

Buy an original in fair working order. My advice.

Discussed a little while ago: https://tubeamparchive.com/viewtopic.ph ... =magnatone

I think I will use a 12AU7 instead of the small 6eu7 tube.

[martin manning]

This might help with the circuit...

I don't know if you already knew this or not, but the 6EU7 is basically just a 12AX7 with a different pinout and no series heater option. I believe it was designed for low-noise phono stages and such, but it's essentially identical electrically.

And great advice it is! I'll be on the prowl for a 440 hopefully in the neighborhood of $400 more or less. That's what I can guess anyway.

Good to know. All I knew was 9 pin and high gain... Not too expensive, but definitely worth trying, once I figure the circuit out.

[Blackburn]

Oh and the pinout of the 6eu7 from my RCA Tube Manual.

1. Filament
2. Filament
3. NC
4. Cathode
5. Grid
6. Plate
7. Plate
8. Grid
9. Cathode

This is the one I've been looking at.

Yes 6eu7 I the same as 12ax7 different pin.I have some mullards and some RCA's that haven't ever been out of they're box.Accept for me to look at them

I keep meaning to use them but I atuomaticaly wire stuff up for ax7's

[cbass]

oh And the filaments are much easier to wire

Yeah this got me thinking about using them. I wonder how different they sound. Curious, since you generally don't see them in straight up amps with no effects.

I want one of your Mullards!

FWIW, my understanding, too. I used a used Mullard in V1 in a JTM45 build I did. Sounds great!

They Are used a lot in the "offbrand" amps

This one is kinda cool and different.It has a gain stage after the PI
