Thicker PL400 faceplate with new analog meters...

[Gepetto]

Opening up a poll to see what your preferences are on a thicker PL400 faceplate (3/16" instead of 1/8") with new meters.

Meters are slightly larger than originals, backlit with slight parchment color meter scale.

Very cool.

This is a 3D PDF so you can rotate it and look over the meter subassembly. No cheap meter clamps used here...professional grade.

Wow, Outstanding Joe.
These upgrade considerations for the 400 are really next level.
Very Nice!

No copper?

Source some killer transformers and you have a bangin’ kit!

Very nice Joe. It's great that you can do this for the Series 1 guys. Wow!

 

[laatsch55]

HELL YES!!!

 

[AngrySailor]

Not very helpful but I’d select all options... awesome to have a product like this in the works Joe.

I'm more of a Series II dude but I will have to look for a donor analog meter 400.............

 

[Mohawk]

Joe, you are the master !

I think gain controls would be a great option...a power switch with soft start or a relay... I know this adds expense and some don't see these as necessary or adding value to a build, but for a lot of us it's a hobby and a nice convenience.

Gain Control????????? You mean you want to add the "Little Distortion Machines"??? I'm all for volume pots too. Maybe on the back side of the new face plates, Joe can have partially machined holes so drilling for the pots can be done by the builder very easily. An "Added Option" so to speak.

OMG not them little buggers

I'm sure we can find pots that cost a little more than $2.00 to keep the distortion (that you'll NEVER hear), down to a minimum.

I got some off these.

I’m sure they are from a noise free environment

Attenuator made a massive difference in my headphone amp. But that is much more revealing a circuit… nothing is best but that’s next in line.

 

[Oldskoolfan]

Maybe I should have written variable input attenuation control device?

If those are stepped attenuators, isn't having only 5 positions leave some big jumps from one setting to the next? I suppose that the preamp will take up some of that. That's the one thing I didn't like about the Pro 700's. But setting the attenuators on the amp to about the 2-3 O'clock position and then using the pre made it just right. I also used a regular PL-700 pot on them in some cases.

What's the diff?? Same-O Same-O...... they accomplish the same thing.
