    Newbie to tube amp question - can I plug directly into this unit with my turntable? Or do I need a pre-amp? Thanks

    You need a phono premap -then from that into the line level inputs. Line level accept everything - like CD players, Tape - etc - phono needs to be brought up to Line and a few more things (that the phono pre does.)

    The new ST70 has two volume controls on front - one for each channel.

    Thanks for your help. I have a vintage sony str 6800 receiver, can that be incorporated. Or do I need new gear? How much does a decent phono preamp and line level go for?

    Fill out your info profile so people can help you - ex what turntable, cart, speakers etc.

    You can get a very nice phono pre for a couple hundred bucks - and of course you can spend much more.

    It also looks like you might be able to use your Sony as a preamp - and then use the Dynaco as a dedicated amplifier - I think that is what is meant by the ext outputs and ext button. And if you are happy with the Sony and it has a phono - then that is enough for now.

    I think you are fine with your Sony - use that as a pre-amp - and the Dynaco as the amp. If you have a CD player - you can try that through both the Sony and the Dynaco to see/compare what you like best- my bet would be the new Dynaco as the Sony is fairly old and I'm assuming it hasn't been rebuilt. Typically those old 70s receivers can get really noisy and flat/boring in the soundstage dept - until they are refreshed and gone through by a tech.

    If you want more info and more opinions - start a new thread in the audio hardware area - lots of folks watch that.

    Thanks,

    I emailed Dynaco and asked if the ST-70 can be used directly with a CD player. Here is the response I received:

    Thank you for your interest in Dynaco. While you can connect a CD player directly to the ST-70 without a preamplifier you may find it hard to set your levels for appropriate listening comfort. You can absolutely try it to see if it works for you before investing in a preamp.

    Been procrastinating, but went ahead and ordered one today. I have a lot of NOS EL34 tubes I’ve stocked up on for my guitar amps, so it should be interesting rolling output tubes. Looking forward to it!
