I was thinking about how much I like the clean tone of the Tweed BluezMeister, but that it would be cool to have reverb and vibrato like on a Deluxe reverb. So this is what I came up with. Haven't built it, but I'd love to.
CHECK for errors!! Any discrepency, go with the schematic which should be correct.
IF you don't want to use a phase invertor plate 10k trim pot, then I'd suggest using a 120k & 110k resistor for the plates.
With respect, Tubenit

At the risk of being dumb, which Deluxe reverb circuit did you decide to follow?
My schematic list shows several CBS era circuits.

And even the reverb & vibrato are not the same. I also used a tube rectifier unlike a D-style amp but similar to a DR. And it uses a fixed bias 6V6 power amp like a DR. With respect, Tubenit |

hi
just learning ,,
6v6
does pin 8 ground need a resistor and cap
like 25uf 25v ,,,, 250 ohm ,10 watts

like 25uf 25v ,,,, 250 ohm ,10 watts This amp is fixed biased instead of cathode biased. So no, it doesn't need a cathode resistor and cap. You could build a cathode version if you wanted but the vibrato circuit would need to be modified. With respect, Tubenit |

Check v2 for validity. I noticed this valve had two triodes in parallel. Care to discuss this approach?  |

Check out a schematic Princeton Reverb, Deluxe Reverb, Super Reverb, Twin Reverb ................ etc....... With respect, Tubenit |

hi
well i have been looking and wondering about V4.
should ...........
16 ,,,,,,,,,,1M to ground line .
15 ,,,,,,,,,,,wire to bottom 16
1M
pin 3 V1 4.7 M resistor to ground
heres a pic
thanks
tom

I don't understand what all your questions are?
Go with the schematic if there is an error between schematic and layout.
There should be a 4.7M resistor to ground from the .002 to mid-boost switch on the layout.
Remember, this is a DRAFT idea. As far as I know, no one has built this.
With respect, Tubenit
