Dynaco PAS 2 value and difference to PAS 3?


I have an opportunity to buy a Dynaco PAS 2 but wonder how much it is worth. It is stock and works fine. Just looking for a rough estimate.

Also what is the difference between it and the PAS 3(X)?

thanks for any information

I just picked up a Pas 2 that looks just like a Pas 3 so I assume it is a later production model. IMHO bypassing the tone controls is a instant upgrade.It eliminated a lot of noise and it is so easy to do anyone with any soldering skills can do it in no time at all.The benefits are huge!
I plan on doing many upgrades to mine,but first will be the potentiometer and the power supply.The power supply upgrade is very inexpensive and makes it a much safer piece,not to mention (from what I understand having not done it yet) a sonic improvement.
This is my first tube component in over 30 years of solid state sterility. So far it is nothing but fun to hack on and sounds amazing.Old and funky?sure, but it is cheap and fun for hacking and the sound is way better than any SS preamp I have ever heard.

btw Viridian and Ralph Atmos are very experienced and are guys to listen to.

Ralph here is my progress and plans.

I have bypassed the tone controls. All the caps have been replaced.(orange drops from the looks of them)
I replaced the funky bad balance volume pot and disconnected the loudness feature.
I added a couple of 47k resistors to the volume pot to help the taper.(much better)
I have a stepped attenuator coming.
I have a power supply upgrade board coming to get rid of the rectifier, but keeping the tube.

I would like to eventually get rid of the blend switch and the tape eq for more inputs, but that is low on the priority list. I only listen to LP,CD,FM and I have enough inputs for those already.

I have my SUT connected but I had to go back to the 15:1 ratio because there was too much gain. No problem.
It sounds so good. I am in tube heaven. Those old Telefunkens are sweet.

I feel like I have never really known what "inner detail' meant. This has inner detail in spades. Not to mention timbre and presence the likes of which I have never known.

I have to mention that I got a lot of help from George Regenesis. He offers Dynaco upgrade boards and was a big help to me so he deserves a shameless plug here. He also has some of the best prices too.

Ralph, would this mate up with the Atmosphere's MA-1?
I really want to hear those amps.Of course I would need some Zero transformers too.
I can't wait to go back to work and making a living.

Ralph, that sounds like it could be beyond my beginner abilities unless I had directions.I think that the impedance values are kind of weird, but I can live with it for now.Very sensitive volume pot.

I saw that there is a guy that offers new "Spice" designed boards that incorporate 3 tubes on each board. Interesting!

Regenesis and Dynaco Doctor both offer new boards.
Are these updated circuits/caps or are they just replacements?
