6K6 Tweed Overdrive D-inspired

Post by 10thTx »

IF this should be moved to a different thread, let me know or feel free to do so. This is a D-inspired design & the schematic and layout are here:

https://tubeamparchive.com/viewtopic.php?t=17500

So, I recorded this at a volume that would be about the same as a VibroChamp with volume on "6". My guess was maybe 3-4 watts volume max?

NO effects pedals. Delay, compression and EQ added in mix.

I used 12AV7 tubes in the preamp (along with 5879 pentode), 12AT7 in the LTPI, 6K6 power tubes and 5Y3GT rectifier.
PT is a 275-0-275. So maybe around 305 volts on the 6K6 plates?

I was wondering what kind of D-inspired tone I could still get at around 3 watts volume and this is what I came up with.

Is the cathode on V1b mislabeled on the schematic?


The amp (and playing) sounds mighty fine!

Schematic is correct. V1b plate is 150k and the cathode is 2.2k with a 1uf cathode cap.

V1a pinout labeled:
plate 1
grid 2
cathode 3

V1b pinout labeled:
plate 6
grid 7
cathode also labeled 3 (shouldn't it be pin 8?)

No big deal, just thought I'd mention it.

Yes, you are correct. It should have been pin 8. :wink:

I misunderstood. I thought you were meaning component values.
