The 6BQ5/EL84 twist

Along the same lines, some folks have old tube radios that use 6BQ5/EL84 power tubes. Russian 6P14P series power tubes have been marketed as equivalent or superior to the good American and western European 6BQ5/EL84types from years past. Be careful.

The end letter designations are crucial. The 6P14P-EV (rated 5000 hour service life) and the 6P14P-ER (rated 10,000 hour service life) are the more worthy ones. Other variants of this series of power tubes have been prone to failure or short service life.

Good luck.
