Tung-Sol EL34B reissue - precision matched

Tung-Sol EL34 / EL34B reissue - premium matched
Manufacturer: Tung-Sol (reissue)
These new production Tung-Sol EL34B power tubes have a higher impedance design with increased responsiveness and a hint of the 6L6 sound. Price includes extended burn-in and precision matching. 
These tubes have been burned in and tested at typical operating voltages on a laboratory grade Amplitrex AT1000 (manual setting, fixed bias mode). They are precisely matched for both current draw (mA) and transconductance (Gm). Learn more about our burn-in and testing process here.

Price is for a single tube and includes burn-in and standard matching service. Tubes ship in Tung-Sol retail boxes.

Precision Power Tube Matching

Our power tubes are burned in and then tested on a laboratory grade Amplitrex AT1000 tube tester. We match tubes for both current draw (mA) and transconductance (Gm) at typical operating conditions (plate: 500V, screen: 450V, grid bias: -41.5V).

After burn in and testing, we hand select and custom match every power tube order we receive. To do this, each power tube set is also run on a custom, fully variable test fixture that can match the operating conditions of your amplifier based on the information you provide below. This enables us to do a final check of the power tube set's performance and matching under load. Why this matters
1. What is the manufacturer and model of your amplifier?
2. How is your amp biased?   Why we ask
3. Matching notes   Why we ask
If you know the plate, screen, and grid bias voltages your amplifier uses, please note them in the comments section when you check out and we will use this information when we select and match your power tube set. (If you don't know, don't worry--we can make an educated guess based on your amp's make and model, if we don't already know the voltages it uses.) If you are a guitarist, you can also specify if you prefer early or late breakup. Thanks!
