    hey there

    So I am moving and I came across a bunch of just amazing EL-34 power tubes. Got me thinking about getting an amp designed around EL-34s but you don't see a lot of bass amps designed around EL-34s. Is there a reason for this? Seems like a nice VR-4 type Amp could work wonderfully.

    I had a Traynor YBA3 and it used EL-34's. It sounded wonderful kinda of Ampeg-ish but with a somewhat different growl but, it was not reliable. I don't know if that is a characteristic of the tube or the way the amp was designed.

    If you can swing it, get a Sadowsky SA-200 to put those babies in, muy bueno.

  4. The Traynor YBA300 is able to use 6L6GC and EL34 power tubes. But ya gotta have 12 of the suckers! Very nice amp btw

    In the UK EL34s were / are just about the only output valves, sorry tubes, used in 100w heads, so any UK 100w head is what you need. Marshall, Hiwatt, Sound city, Orange, the list is virtually endless and In my opinion, they sound a lot better than 6550s.

  6. Aus was similar. My old/1st amp was an Aus made Eminar 150w amp with 6 EL34 power tubes. Built in Melbourne in early 70s. Sounded good too!

    Same goes for 50W heads. A pair for 50W and a quad for 100W. A superb tube for bass IMO.

  8. I've used a 70s Traynor YBA1 for over 20 years, and it's the most reliable, bomb proof, idiot proof amplifier in the known universe. It uses 2 EL34s.

    The original Music Man amps (65 series and HD-130 series) used 6CA7/EL34

    Here is an interesting power tube comparison with a guitar.
