Thicker PL400 faceplate with new analog meters...

[Oldskoolfan]

Good morning Joe,

Out of curiosity, if you decide to have the new faceplates (thick or standard) made when do you think they would be available and what would the ballpark price point be? Looking at a full comp WOA rebuild on a "Val" PL400 and working on a budget.

What is length and width of meters?

What is length and width of meters?

5" wide by 2.5 tall. The frame will occlude a bit of that on purpose...

Hello Harold
I have not worked that up yet. Faceplates without meters have gone for ~$100 to date for the PL400/700S2 and the PL700B

It’s now the WOA 410.

Joe hate to ask, but are these meters 100 percent all-inclusive and new or do we still need our old ones?

 

[laatsch55]

All new Jer..

 

[jbeckva]

Cool. I've had 400 8 finner that in a momentary lapse of reason gave one of the meters away. Or was it a 700 set, hell I can't remember it's been so long since I did the last WOPL.

Survey says (thanks for all the input):
Without attenuators:


And with attenuators:



Hopefully something for everybody (even has lime green for Perry's knobs). Pilot holes are back drilled on the back of the plate in the locations shown for installing pots if desired. User will have to complete drilling them out from the backside if desired. Embodies illuminated power switch, meter range switch. If pots are added, the design is for a 32mm (1.25") diameter knob.

Looks nice- It would be interesting to make one 700B style as an option...

Well, all that's needed is a source for transformers and cooling fins then you could sell complete DIY kits.

 

[Gibsonian]

Cooling fins are already available. Transformer is the missing link.

Looks great!
Timeline for availability? I'm trying not to rework my original faceplate!

I assume the the attenuaters are just wired inline with the RCA inputs? 100k?

 

[J!m]

Could the WO circuit be tweaked to accommodate a readily available transformer?

Torroids can be wound to taste but I would maybe try for an R-core if going custom.

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.

It would be nice to add Level Potentiometers on each side of the attenuation toggle, with a very low cutoff DC-Block....just in case preamp is DC hot. I'm doing this stuff to mine.

Same one Ronnie, just different mounting holes on each side and the silkscreen change from 400 to 700

Now there is a thought...

Yes and whatever value you decide to purchase and install...

I have designed and prototyped a souped up PL700 transformer. The unfortunate part is that they are just not affordable...

Is Bob Carver's brother still winding transformers?
