I want to buy 4 brand new Siemens el34 tubes for my Dynaco ST70. The price is $40/one. Is this good price? How can we match quad EL34? or we just biaset voltage 1.56V. I am new to tube amp so I need help. Thanks again.
Where did you find brand new Siemens tubes?Do you mean NOS?I don't think Siemans have made tubes for many years,but,I could be wrong,have been before.I'd hate to see you buy something that was misrepresented.
My friend in LA has couple brand new Siemans EL34 tubes for sale. I want to buy them but no clue on quad for my Dynaco ST 70. ST70 has biaset voltage only.
First, you don't need a matched quad of tubes for the Stereo 70. What you need is two matched pairs, as bias is adjusted by the pair. This usually makes it a bit easier.
In my opinion, the Simens are not particularly good sounding tubes, and for much less money you should be able to get very well matched pairs of tubes by JJ Tesla, SED, Electro Harmonics, etc.
