Earlier this week I accidently hooked up the fixed output of a tuner which sent the full power of a Proton d1200 power amp into my khorns. Why are those rca jacks so close together and so hard to read especially in the dark on a chrome chassis. Thankfully the 1 1/4 amp fuse on the horns blew quickly. Once my heart rate got back to normal (100wpc into 105db sensitive speakers is stupid loud in case anyone is wondering) I started thinking how glad I was that those blown fuses weren't the $100+ type. Plus those generic fuses did their job and saved the horns from certain destruction.
The Frankenaltecs are in the midst of a heart woofer transplant.
Since I am only using the woofer sections of the 604Es at this point anyway, and since the opportunity presented itself, I am swapping out the Duplexes for a gorgeous (and - currently - borrowed!) pair of 515Bs.
One down, one to go.
I fired it up to give a listen -- and I cannot stop long enough to do the other one.

Does the "B" stand for back so you remember which side is which? Yeah, I'm old too...

You mean, like writing "TGIF" on a pair of sneakers?
Toes go in first.
Close!
The cabinetmaker labeled one enclosure "A" and the other "B". The backs of the baffles are likewise labeled A and B. The speakers are also each labeled (1 and 2)
I actually have the measured T/S parameters of "1" and "2" so... it sort of matters. They are, fortunately, pretty close (not a given with drivers that are as old as I am -- perhaps even older).
PS both cabinets are now rewoofered with 515Bs. I had a town Finance Committee meeting tonight, so I haven't heard the pair -- yet.
I've been using Denon LO and HO MC's for a long time and never had an issue. gmcman, PM me if you want I may have a spare I'd let go but I'll have to take a look.
Thanks, I appreciate that.
I did pick up a new cart anyway, but never can have too many. I went with the Audio Technica 33PTG/2 and pretty much have it dialed in, but need to get back to it tomorrow. Also need to find some shorter screws.
This is in conjunction to the Cardas tonearm wire and Cardas Spiral air 1M interconnects, both are Litz style wires.
The results so far are excellent, I'm taken back at the moment at the level of air around the entire audio spectrum. Not overwhelming, but that sense of "being right there" really stands out, and not bright by any means, the highs are well controlled throughout.
I will revisit this, but for now I wanted to share my experience in leveling the table. I used a Starrett 98-8 level to get as much accuracy as I could, even though my regular bench level is adequate, I feel any amount of added accuracy is worth the trouble.
This Starrett is very sensitive, it will register the difference if I place a piece of register recipt under one end, each graduation is .005" per foot. The level would pick up a few deg of movement of the feet so this was a tedious task.
I've had good results with this mat, but cannot use a clamp due to he recessed center. Not trying to bash it, but was surprised at the deviation...and this likely wouldn't be an issue but the thickness varied at many points.
Once I realized this, I used a pair of calipers on the mat. The thickness varied from two points, 180 deg apart, from .1975" to .2060. This is somewhat depicted with the Starrett.
I'm currently using the stock rubber mat which is pretty much level, only a small variation but almost .009" across the other mat is still significant...unless I'm way overthinking it.
If you have the 1200, I highly reccommend at least these wire mods. This current setup is quite the upgrade from where it was.
Doing some re-freshing testing today. This combo doesn't suck.
Dual 1229Q into Pioneer SA-8100 driving a pair of Infinity Column II. Full disclosure: I was missing the left channel, so had to refresh headshell connections, and then all was well
I love these types of tests

It wasn't today but last Friday. I was working from home (very sick dog) and during lunch I decided to calibrate the system again seeing as we have added some art work to the walls. I also decided to lessen the toe in and kept the large speaker setting Audyssey chose and to my surprise the system sounded better than ever. The sound stage increased and there was a big difference in instrument/vocal separation.

Finally got around to doing the crossover mod in my 7B on the right speaker. Sounds like a veil has been lifted. Much more clarity. Won't wait long to do the left one! 12 gauge OCC solid wire for the midbass because I wouldn't have been able to get to it later. Was going to do the wires as stage 2 but had to do it this way due to the huge size of the 34 uF cap.

Don't start measuring the thickness of your vinyl (or look for warps)...then you'll really drive yourself crazy.

I don't know if anyone's making transistor socks (or IC socks, for that matter).

That'll make the rig sound too sterile.
You'll need a pair of walken shoes to go with those tube socks.
Sometime this year!
