Nice 70's vintage NOS Mullard EL821 output tubes in the original boxes.   EL821 is a pentode output tube that can match well to output transformers designed for EL84 or 6V6 tubes. Price is per tube. Offers considered for quantity 10 or more
This item is shipped from Britain, in North America or Asia please allow 2 to 3 weeks for delivery.
.

Please note that to use these to replace EL84 tubes, connections must be changed on the socket, these are not "plug in" replacements for EL84 - (the screen on EL822 is connected to pin 9 instead of pin 8, and pin 8 is the suppressor, which must be grounded or connected to pin 3)

We have adapters available to enable replacing EL84 with EL821.
