M19 woofer swap & tweaks....

Ok, so I mentioned in an earlier post my newly aquired 416-8c's that I wanted to compare to the stock -8B's in my 1978 vintage 19's. I've always wanted to test this. This is no scientific test by any stretch of the imagination in fact it could very well be invalid do to my limited amp/source selection (no tubes, no vynil) and the fact that the HF drivers are still the Alnico 802-8G's. Just playing around having fun is more like it I suppose.
Some of my pics tht follow are nothing new to 19 owners, but might be useful to those new owners whom have not yet peeked inside the cabinets.
First pic shows the removed 416-8B and you can see the original internal wiring I've replaced because of the solder joints were extremely weak and near breaking. Also you can see my non-stock bases and that I re-routed the connection leads to the back of the cabinet.

I've also put a bead of clear silicone caulk to effectively seal the upper & lower cabinet sections.....While I had the woofer out I gave the veneer a good wipe with oil polish.

Here is the 416-8C compared to the 416-8B. Member dgwojo gave me these covers sometime back but I still have not come up with a way of attaching them with out altering the cork gasket....something I do not want to do. Someday I'd like to mount them for obvious reasons.

The 416-8B's have a yellow grease pencil mark over the stamped number on both woofers. Although this one looks like an "S".....the other is simply a straight line. Quailty control approval maybe?

In this pic....The LEFT speaker still has the 8B....while the RIGHT speaker has the 8C. I switched the Sansui to "mono" and did went back & forth between both using a variaty of music. Metallica (the "black album") Some Paul McCartney.....and some classical stuff on the Telarc label.

The EQ you see on top of the reciever BTW is not even switched into the system during this. It is just a toy I play with sometimes.

In this picture both speakers now have the 416-8C's installed.
