## 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.
