Went to buy Vandersteen 2C speakers and came home with a conrad-johnson Premier 11A.


I found a great deal on a pair of Vandersteen 2C speakers with Sound Anchor stands.  I didn’t need them, but they are identical to a pair that I had back in the 90s.  While I was there, the seller mentioned that he had an amp that he wanted to sell.  It was on a shelf in a basement collecting dust.  The price was right, so I bought it.  He said there are about 40 hours on the tubes.  Hopefully, the caps are ok.  I’m thinking I’ll try a Wiim Ultra streamer with volume control just to see if everything works.  I have old preamps by NAD and Rotel, but they aren't good ones.

Is there anything special that I should do before firing up the old girl?  This is my first tube amplifier.

I'll see if it works properly before I send it to c-j.  I've spoken to Jeff at c-j.  A few years ago, I had purchased a Premier 17LS2 preamp that had an issue.  I opted to return it to the seller for a full refund instead of messing with repairs.  On the way back to the seller, FedEx dropped it and all of the large capacitors came loose.

I sold a PV-14L when I bought the 17LS2. I should have kept it. I could use it now.

At what voltage should I start?  How slowly do I increase voltage? 

 

Probably best to Google to voltage and times with the variac, or better yet check with CJ.  

Make sure you have that amp connected to a load before you turn it on.  Many tube amps can be damaged if you turn them on without being connected to speakers.

The 11A is a very good amp.  A friend of my late wife, having heard our system in the mid '90s wanted a high end setup.

On a trip to Sound by Singer she bought a pair of Martin Logan speakers (cat proof), the 11A, an Audio Note pre, Ayre DAC, Theta Transport - I forget which TT and cartridge.  She preferred the 11A to the VAC 80/80 that was in my system at that time.  BTW the 80/80 is still going strong - I traded it to my pest control guy for lifetime service!

The Theta and Ayre died about 10 years ago and were replaced by an integrated CD Player/DAC.

The 11A is still playing beautifully - on its 3rd set of 6550s I think - and original small signal tubes.  I believe that CJ use electrolytic caps only in heater and bias circuits.

I now have the successor  - a few generations on - to the 11A - the Classic 62 SE.

 

@knotscott I’ll do some research before I try the variac. 

@seikosha Will do.  The plan is to use the Vandersteens 

@retiredaudioguy Thank you for the information and story.  I hadn’t planned to use the c-j in my main system, but I might have to give it a try. My system is built around a solid state Coda amp.
