Loudness - Why has the industry stopped producing amplifiers with this feature any longer?
Just for kicks...  Check out Luxman integrated and control amplifiers.  They have well designed Loudness circuits.   
Problem with Ref 5SE
So...  Just an observation.  All of my ARC amplifiers over the years have had metal tops.  My VT200 had 8 matched-pairs of 6550’s.  And, a small pile of 6922’s, as well.  It made a great space heater in the winter.  ;-) 
Problem with Ref 5SE
So...  For what it is worth...  I have had no heat problems with either my Ref 5 (metal top) or Ref 5se (plastic top).  Even had both in a media cabinet at one point, with only about 12” of head room.Just sayin’. 
Problem with Ref 5SE
I have a Ref 5se and had a Ref 5.  Both were dead silent into multiple amps.  Speakers:  Martin Logan Summit x and B&W Signature 30’s.  Both very revealing.Stupid questions:  Are you using the CD input and balanced interconnects?  Have you tri... 
Audio Research VT100 MK1 and LS15 HELP!!!
To clarify my earlier post, test the preamp without a load.  No input cables attached.  No output cables attached.  See if the sparking stops.If not, steal a 6922 from the VT100.  It has 8.  Swap it in for the sparking LS15 tube.  See if it fixes ... 
Audio Research VT100 MK1 and LS15 HELP!!!
So...  Just a polite correction.  The jumpers do not go in the XLR socket.  The receptor is separate and apart.  See the manual. 
Audio Research VT100 MK1 and LS15 HELP!!!
Sorry.i did scan them and apparently did a bad job. 
Audio Research VT100 MK1 and LS15 HELP!!!
The balanced input impedance is 200K.  SE is 100K.  Big difference.  IMHO.  Check that first.Do you have a multi-meter with spring-loaded hook clips?  If so, check the amp bias to make you have power.As to the LS15, disconnect it from the amp (pow... 
Audio Research VT100 MK1 and LS15 HELP!!!
You can download the VT100 manuals on the Audio Research site.  The manual shows where the jumpers are. 
Audio Research VT100 MK1 and LS15 HELP!!!
On the rear of the VT100 mki there is a place for inserting jumpers to change the inputs from balanced to SE.  Was the seller using balanced or SE Interconnects?   
Audio Research VT100 MK1 and LS15 HELP!!!
Are the VT100 SE jumpers in or out?  FYI.  I have had a VT100 mkiii and LS25 for years.  And, I own the Luxman DA-06.  Output is twice + that of your Sony.May be able to help. 
Recommendation for higher power tube amp
So...I may have what you need.  I have an ARC VT100 mkiii, an ARC VT200 and a pair of ARC VTM200’s.  All are recently retubed and in 9/10 condition. I am the original owner of the VTM200’s.  The other 2 were demos.What I like about these amps is t...
