I'll take a look, I played a Bloomfield a few weeks ago and really liked the amp.
What kind of reverb tank and where does the 390pf cap connect to? The layout is abit unclear about where the tie points are?

Re: Thinking Through Sourcing PT/OT for D-Lite-ish Build

Find yourself a Crate Turbo Valve 50 or 60 watt from the 90s perfect donor mine came out fantastic you could either use 6L6 or El34 it even had an auto bias feature! You can pick a complete donor for around 200.00! :) Perfectly good cheap American made Iron

Re: dechiphering an output transformer

Blue plate Brown plate wires is there a certain polarity or doesn't it matter which output tube pin 3 they get soldered on? Its a typical push pull 6l6 40watt amplifier the schematic shows V5 is Blue pin 3 plate and V4 pin 3 is Brown. But that is backwards from amplifier I pulled Transformer out of?...

Re: Brown Note D'Lite 44 Schematic ??

I have a question I have decided I want to build this particular layout it has a reverb in it! I know I will have to change some resistors because I want to run a pair of 6L6s what all will I have to change and what B+ voltages will I have to modify in the power supply? I have heavy transformers and...

Re: Capacitor cocktail - types, locations

I know 715 and 716 series caps are the standard for most of the coupling but did anyone ever build a Dumble using inexpensive Chinese polypropylene or Polyester caps? Just curious if anyone ever did like those small brown epoxy coated polypropylene films??

Heck just give me my Sencore Mighty 7 or an old Hickok anything beyond that put the tube in the Amp and listen.

Re: john mayer's two rock??

This tone is amazing... Taylor did a fantastic job what are you using for the overdrive?? I know the amp has a master vol..?? Some kind of a boost or pedal?? I mean I understand the normal ODS style Dumbles with the extra gain stage. This looks different for sure? https://youtu.be/RnA0cHdkyHc

Re: Robben Ford's new amp and speaker

Sounds like he's running his guitar signal through a Pixelator??? Whoaa?? I guess he got bored with his old Dumble and decided to try and " fit in" with his new life in Nashville scene? Well, he probably figures at his age he only has to please himself musically.. I get that..
