Remote volume out on TAD-150 preamp..options?

To tide me over I'm using a passive preamp with a remote volume control(source>DAC>preamp>passive preamp>amp>speakers).  

I works and sounds fine.  The preamp itself works as it should..it just requires manual volume control..which is not me.  I use the remote volume too much to replace it with me getting up constantly.

So if it's only the remote that doesn't work then place a Placette Remote Volume after it. They're around $400 used and when you eventually change pre-amps you can sell the Placette for almost what you paid.
