Electro-Harmonix 6CA7EH (High Plate Current)
What are these tubes good for?
- Amplifiers that already have a very wide range of bias range available. For example, hifi amplifiers designed to use a range of tubes from EL34 to KT88. These amplifiers will already have more than enough bias voltage to dial-in these 6CA7 tubes properly. We find they need bias voltage closer to 6550/KT88 tube types.
They test as new in all other respects and will carry our standard 90 day warranty.
Designed to the exacting specifications of the Philips 6CA7 tube, this classic tetrode returns to life in a big bottle design. The Electro Harmonix 6CA7 is built to withstand today's high-gain amps while still retaining the detailed tone and component integrity of the original. The 6CA7-EH A direct replacement, with military reliability, for any EL34.
