Dumble Lite Layout
Here ya go. Simplified switching, Deluxe iron, 6V6s, all stuffed into a 16x8x2 Hammond chassis. Parts came in right at $300 (including JJ tubes) using the usual retailers. [img1247]http://bad-domain/DumbleLite/DumbleLite16x8Layout.JPG[/img]
Re: Dumble Lite Layout
Normster, you are to be praised! This looks like a solid and inexpensive way of obtaining some great tone. Thank you!
Re: Dumble Lite Layout
Very nice norm:) I started gutting one of my princetons last night to try this...
I am still trying to debug my old odsr from your layout.. i have fuzziness around the tones real bad on the clean channel.. it sorta crackles then goes away as the signal level drops when holding a note... real annoying:( will figure it though:) I need to learn to use my damn scope...

Hey man, you're leanin on my dream......

Very nice indeed!
I have a 300-0-300 PT,will that do?
Thanks in advance,Ed

Re: Dumble Lite Layout
I think I got all that stuff anyway. Except the pots. Post the Visio pleeze......

Re: Dumble Lite Layout
That should work fine. You'll probably have to adjust the dropping string in the power supply for V1 & V2 to get the correct plate voltages. I used a 300-0-300 PT (Trainwreck iron from Moose) for my last 6V6 Dumble and really liked the way it came out. I was afraid that it might get muddy when cranked but the bottom end is actually pretty tight.Ed de Jager wrote:Very nice indeed!

Re: Dumble Lite Layout
Thanks Normster i am happy to hear that.
Thanks for supplying the drilling templates too you make life a lot easier:)
What i am wondering is what schematic did you use to get this layout?

Re: Dumble Lite Layout
It's just a simplified Hybrid-A. Same preamp values, just eliminated some switches and relays.

Re: Dumble Lite Layout
I've got some leftover Mercury Magnetics deluxe iron, and I've been waiting for something like this for a very long time. (relays are still way beyond me....) anyway, my PT is 380-0-380... would this work? what would I need to change? I love the sound of the deluxes that I've built around this iron......I'm hoping this will do a great job for a d-style as well...many thanks
Re: Dumble Lite Layout
I think the secondary voltage might be a little too high to run a SS rectifier into 6V6's. However, you could change the design slightly and run a tube rectifier and be in the ballpark. IOW, just build the plate/screen power section like a Deluxe. Make sure to also reduce the filter caps so you don't blow up the tube.stompjunkie wrote:I've got some leftover Mercury Magnetics deluxe iron, and I've been waiting for something like this for a very long time.

Re: Dumble Lite Layout
Are the boards in the second screen of the Visio file supposed to match up to the pre-drilled mounting holes in the Brown-note D'Lite chassis?
Re: Dumble Lite Layout
No. The original D-Lite used a shorter board so it would fit in a 16" chassis. The production D-Lite chassis is 17" and uses a longer board (to make soldering a little easier). Check on brownnote's site for the latest layout. It's drawn on the actual chassis blueprint used to laser cut the chassis.drew wrote:Are the boards in the second screen of the Visio file supposed to match up to the pre-drilled mounting holes in the Brown-note D'Lite chassis?

Re: Dumble Lite Layout
Normster,
Do you have a BOM for the current version of the D'lite? I'll do one, but I thought may be you already had the work done.
Thanks,
mR

If it has wheels, tubes, or breasts.......
