Joined Apr 4, 2013 So of course, being a baby 6V6, I thought about using this occasion to use the 5E3 topology. Try plugging in to the bright channel, and set the bright volume at 5, then slowly bring up the normal channel volume - it's very subtle, but there is a noticeable boost in the bass as you bring the normal volume up (until you go too far and attenuate the signal). Measure and record the following amp voltages for troubleshooting and future reference: Wall Voltage AC because it affects all the amp's voltages. The same with the Tweed Deluxe 5E3 with one preamp tube less than the TOs amp. Here is a table showing the state of charge (SoC) vs voltage for a typical lithium-ion battery cell: State of Charge (%) Battery Voltage per Cell (V) 100%: 4. If anybody has some info I'd appreciate it. FENDER TWEED DELUXE (5E3) Schematic redrawn by Steve Luckey on May 20, 2006. I like the ’74 Twin, but it is pretty sterile and after a jam session with a friend I realized that I wanted something much lower wattage that had some unique tonal character. For more modern Fender amps you would I also included a switch to change the 5E3 interactive volume and tone controls to a regular resistive divider volume controls. Likewise although you could measure or calculate bias current, and that is handy to check one 6V6 against the other, Rob's "Tube Dissipation Using Cathode Resistor Voltage Drop" method is really quick and easy and accurate; and although it averages the two post voltage chart of all plates and cathodes. Power filtering comes by way of a 20/20/20/20uF cap can. The 5D3 and 5E3 schematics do not have voltages listed. With all that said, a 5E3 is a fantastic little amp to play through and play with, but as already mentioned, small changes can make big differences and be very informative as to what those small changes can actually accomplish. The B+ voltage measured on the tube is 399v.
