D'Lite Schematic

Post by mdroberts1243 » Sat Apr 21, 2007 1:49 am

I have seen a few requests for a schematic of the D'Lite... thought I'd give ExpressSCH a try and here is a (draft) schematic of the D'Lite with Relays from Normster's web page (the one I'd like to build someday).

This is just the circuit proper, I haven't done the power supply and shown the relay coil wiring with panel switches... yet (that will be page two and hopefully have room for power scaling.

I'd appreciate any errors pointed out!

UPDATED: I deleted the old, partially complete schematic from this post to avoid confusion with the ones that follow later...

PI plate resistors corrected

Post by mdroberts1243 » Sat Apr 21, 2007 2:33 pm

This has the panel & footswitch wiring and the power supply page.

UPDATED: Minor tweeks and an error corrected... the 2.2K between power C & D changed to 22K.

UPDATED: Corrected relay power supply.

UPDATED: Corrected PI plate resistor values (swapped 82k and 100k around).

UPDATED: Swapped blue & brown to match above.

UPDATED: Changed V1a Ck to 10uf to align with the current D'Lite Layout

Error correction

Post by mdroberts1243 » Sun Apr 22, 2007 11:51 am

I updated the schematics above to correct an error Drew found on the other forum... Power Supply resistor between C & D was 2.2K should've have been 22K.

Relay Power Supply corrected.

Post by mdroberts1243 » Thu Apr 26, 2007 2:37 am

I corrected the power supply page of the schematic posting... the relay power voltage doubler runs off of the 5V secondary, NOT the center tapped heater secondary.

CORRECTED PI Plate Resistors

Post by mdroberts1243 » Sun Aug 19, 2007 2:50 pm

I swapped the 82k and 100k plate resistors on the PI.
Thanks to AmpGeek on the Brown-Note Forum for catching this!

Thanks alot for this effort Mark. Well done!

But....I can not tell a lie. Dogears pointed out the criss-crossed PI resistors. So...much thanks to him for this and so many other outstanding pointers and suggestions.

Well then, thanks for sharing it with all of us that might've stumbled into a pothole on this! That's just as important as finding it.

Can anyone tell me what PT, OT and output tubes are used in this design?

Many thanks,

Some of the early ones used Vibrolux PT and would run 6V6 and 6L6. Some old info here: http://ampgarage.com/forum/viewtopic.php?t=24293
