Well, after nearly 500 hrs over the past 6 months of obsessive working and draining all my monitory recourses there finally done. I had no idea as to what the finish should look like, I couldn’t get an idea in my head of what I wanted it to look like so I just kept experimenting with different finishes and at the last minute I decided to add the oak inlays, boy did I bite off a chunk there, anyway they kind of look like turtle shells at first so I changed the finish one last time to a lighter shade for more contrast and I’m happy with the effect, and they integrate well into my all Red Oak trimmed living area so I’m quite happy with the looks, although I’m sure some will find them grotesque or just too weird.
Just as soon as I fired them up and got a good listen to wet my appetite and began the arduous task of fine tuning the crossover I turned off all my equipment (Sony TA-E9000ES Pre Amp and matching Amps) to wire in the AR correction networks that Peter has been so gracious to help me with (Thanks Peter at AR) Unfortunately as luck would have it when I turned it back on there was no sound, no output from the Pre Amp at all, It’s done this before but started working after I cycled it on and off again, However this time it was for good. So I opened it up and found two bad transistors (Q108 and Q110), I then posted this on the dedicated TA-E9000ES Forum that I frequent, turns out this is a well documented problem with this unit and within a day Djay the moderator sent me information regarding a service bulletin for the very problem I have and notes “Q108 overdissipated”, and then states that to repair you need to replace a 4.7K 1/10 watt resistor (tiny chip resistor) with a 1W version to protect Q108, I’d like to see how they expect you to shoehorn a 1W on tiny flat pack pads that are .05 spaced (Thanks Sony Engineering).
Anyway, I should have my system up and running in a few days and be able to see if the AR Conjugate filter helped or not, and continue tweaking the Ports and playing with the mid angles and tweeter position.
As soon as I get them fine tuned I’ll try some actual acoustic measurements and some gated pulses to set relative acoustic offset.
