## How many watts is 5E3?

15 watts
The 5E3 Tweed Deluxe is one of the most revered small tube amps of all time. At 15 watts it’s a great club amp. It has been played by greats like Billy Gibbons, Neil Young, Don Felder, Eric Clapton and countless others. It is a truly classic design.

Is 5E3 fixed bias?

Switchable Bias: Fixed Bias / Cathode Bias. The 5E3 uses two 6V6GT tubes and a cathode resistor to bias the power tubes.

How do you measure plate dissipation?

Plate Dissipation in watts = Plate Voltage * Plate Current The Plate Current must be in amps, not milliamps so if you get 19.4 milliamps convert that to . 0194 amps by dividing by 1000.

### How many watts is a Tweed Deluxe?

The amplifier has a 5Y3-GT rectifier, 2 6V6-GT power tubes operating in push-pull mode, and a 12AY7 and a 12AX7 in the preamp. The output is rated at about 15 watts. The Tweed Deluxe originally came equipped with a Jensen P12R speaker.

Are cathode biased amps good?

Cathode bias amps have more sustain and dynamics but a spongier response particularly with bass notes (more sag). Fixed Biased amps have a firmer feel but less dynamics and sustain. One thing to note is that properly set up cathode bias can be quite firm but still singing.

How do you calculate current plate?

Total Plate Current = DC milliamps = Cathode Current minus approximate screen current of 5.5%. Plate Current per Tube = DC milliamps = Total Plate Current / Number of Tubes. Plate Dissipation per Tube = watts = Plate Current per Tube x Plate Voltage.

#### How is tube plate calculated?

How many amps does a 5E3 power transformer use?

So a 5E3 power transformer must supply at least 2 amps of 5V rectifier heater current, 1.5 amps of 6.3V current for the tube heaters and 90.8 milliamps (0.0932 amps) of B+ current. It uses 10 watts of 5V, 9.5 watts of 6.3V and 34 watts of B+ for a total of 53.6 watts, less than a 60 watt light bulb.

How many amps does the 5E3 Deluxe rectifier use?

The 5E3 Deluxe’s 5Y3 rectifier uses 2 amps of 5V heater current. Other rectifiers: GZ34 uses 1.9 amps and the 5U4 uses 3 amps. Heater current in amps: Preamp tubes: 0.3, KT88/6550: 1.6, KT66: 1.3, EL34/6CA7: 1.5 , 6V6: 0.45, EL84/6BQ5: 0 .8, 6L6: 0 .9, 5881: 0 .9

## How does the 5E3 preamp tube work?

The 5E3 uses a 12AY7 preamp tube for the first gain stage. You can substitute a higher gain 12AX7 to boost amplification, reduce headroom and increase breakup and distortion. The preamp tube amplifies the guitar audio signal then sends it out pin 1 (plate) to a coupling capacitor or ‘cap.’

What does the signal flow look like on a 5E3?

The signal flow is identical to the 5E3 and is shown using orange arrows. Red arrows show the power flow. My first amp build was a BootHillAmps.com 5E3P.
