I need Help with this tube "8CW5/XL86

[John Fisher]

Hello all,
I am presently getting ready to build a "Tiny Terror" clone. I made a trip to a nearby city to get some EL84 tubes for the amp. On the box it said "EL84" and "6BQ5". The brand is Pro Comm.
When I got home I opened the box to find that it said "8CW5/XL86 Japan"

When looking on line this did not match any of the substitutes for a EL84 tube and I found little information on the tube.

Does any of you tube freaks out there know anything about this and is this tube really a substitute or is it just another way of calling it a EL84?

Thanks for your help with this.

looks somewhat similar, with same basing but bit different ratings, heater(also looked in my GE Essential Characteristics)

Friends of the 6L6 - Some power tetrodes and pentodes

looks similar as well and as with the 6BQ5/EL84, apparently some (heater number)CW5 were beam tubes.

sorry I don't know if it will be an adequate sub

It's the 8 volt heater version of the EL86.

Doesn't seem like a very good EL84 substitute.
