a tube amplifier repair technician

So how is it going? I could have sworn I wrote to answer by suggesting
even the upgrade to the HiFi Tuning fuses at $30 (now they seem to be $40). But my response isn't here. ? :S
I talked to Bob, and I'm sure you have since. So how did it go?

From my original conversation with Bob about possibilities to improve the already superb Vandersteen Quatros , I concluded that Bob's confidence level with work that could or was necessary to bring these speakers to another level was pretty low. I felt that since Bob's enormous knowledge with circuits, preamps, amps and such was so great that some parts of Quatro's design could be at least looked at and possibly upgraded with better quality parts, wires etc. I still think that power modules (bass amps) can be optimize to sound their best. Maybe even the external crossover could use some modification to sound even better. I am not aware of the quality of internal wiring but that is another area that can be addressed with quality wires that would somewhat close the book on the Quatro mod.....at least those are the areas that I would look for the weak spots and would start there. Of course it doesn't mean that there is something wrong with my speakers but why not ...at least try to make them even better.
I am not sure but I think that Bob wasn't sure if he could actually make them better, that is why he sort of backed off from the attempt to modify them. Well, I do understand his reasons and I never try to pushed him into doing something that he wasn't comfortable of doing in the first place.

I might try few things but I still believe the bigger improvements can be made in amp, wire and crossover of Quatros. But that is just me.
Right now I am in the middle of trying few new components in my main rig as well as in the second system so it is not really (mod) on my priority list.

Mariusz, at this point, it may be time to introduce you to a person who does for loudspeakers what Bob Backert does for amplifiers - Bill Legall of Millersound in Lansdale, PA. You can reach him at (215) 412 - 7700 and http://www.millersound.net/indexfl.htm or read a bit more at http://www.6moons.com/audioreviews/roadtour13/roadtour13.html

I would venture to say he's never worked his magic on a pair of Quattros, but as anyone who has heard what he has done with Vandersteen 2, 3, and 4 will agree, the transformation is pretty incredible.

Joe, I own you one.
That is what I was looking for.
To be quaite honest I was going to ask you that before but I did not want to give you the wrong impression.

as alway.......there when it matters..........Thanks.

happy father's day ...

i called bob backert, on a sunday, on father's day, and he took the time, with patience, to walk me through the diagnostic scenarios of my fisher tube amp problem. it was a simple fix, this time, but i wanted to share his generousity of spirit (and quick troubleshooting!) with you all.
