That Tube was made 20 -25 years ago. The T Series Tubes were followed by two seperate Tubes, the EL Series and the RS Series. If memory serves me correctly this was in 1995 (maybe 1997, I don't have the exact date in front of me).

Thanks for everything. Feel free to delete this thread.

heavyduty,
you seem to know everything so i'm hoping you can help me. can you give me the specs to this bazooka . . . http://cgi.ebay.com/Vintage-Amplifie...item2a0e3fbc56
when i was in high school my friend had two 6 in bazooka bass tubes, one amplified and one passive. He had the passive wired into the powered and they sounded excelent. I have bought a coulpe tubes in the past few years hoping to get the sound i remember, but cant. I'm hoping this might be very similar to what he had, but just cant for the life of me remember for sure what they looked like.
thanks in advance

Please post back with any other questions you may have.

thank you
I'm noticing on the wiring diagrams for all of those, there are only wires for hi level inputs. I know for a fact from what i remember, the one tube was amplified and the other passive tube was wired into the amplified tube and got its power that way. If i got one powered and one passive, isnt there a way to do this?

Yes. You are confusing the High Level Inputs (signal) with the High Level Outputs (which connect to the slave unit). The Green and Grey wires are for the High Level Inputs while the Black wires are for the High Level Outputs.

also i find alot of info about the bta250 but cant find much about the rsa or ela tubes. which of the three do you think i might be searching for? also im not quite sure about the matching passive tube. for instance if i got the bta250 would the bt6024dvc be the ideal mate?

The T, EL and RS Series Tubes have all been discontinued and replaced with the BT Series. You can still view or download EL and RS Series owner's manuals on the website. The BT6014 is the correct slave unit for the BTA6250D.

thank you very much for all your help. I have one more question. The bta6250d is 2ohm stable correct? and if i have the bt6014, how would i wire the both of them to operate at 2ohms?
