I made 4 or 5 attempts on some foilcals, but nothing looked acceptable.

You guys may have missed this New Foilcals on eBay thread, and the earlier Foilcal Replacements are Available. These look near perfect.

btw, John, I've followed closely your contributions to this thread - that work looks excellent...

Thanks.
Actually I finally broke down and purchased foilcal and grill plates from another forum member who had them made up by Kenji.

They are very nice, almost perfect reproductions. I don't think the member I bought them from has any left. Plus, he got a speeding ticket on his way to ship off the package negating any profit and probably removing any incentive to bother selling any again. Still, thanks a ton

They may still be available from the source.

Hello John W .

Sorry What do you mean by side of the resistor .
Does the wire has to be on one only side and why ?

Here is an other pic

[John W]

Current from the battery flows throught the resistor to charge the capacitors. You have it correct, except for the connection on the far right. This one has the battery connected directly to the capacitors, it isn't in series with the resistor. Have a look, the resistor connects from the capacitors to a dead end.

Maybe this will help...

[gerard]

Ok

I will correct it and look at the other Xover .

May be I shall post a new pic of both Xover after so You might be able to check again .

Thank's again .

Thank you for comment if anything has to be changed .

Are the side panel 1x3 bracings physically attatched (glue,screws) to the front baffle and rear panel? ..or just a snug it?

Additionally, are the 1x3s that brace the mid 'dog-box' attached via screws to the rear panel or to the adjacent vertical rear panel 1x3 bracings.

I have seen a few threads describing wedges to sure up that axis, but nothing describing physical attachment. I would imaging that end-grain glueing to the front and rear panels is not an optimal scenario.

Thanks

Hi Mr Blog,

I screwed through the bottom of the brace into the dog box . I also put a fillet of consruction adhesive around everything that I had joined . Mine is only one solution of many . Good hunting

Hi Rich,

Did you also screw the dog box brace to the rear panel, thereby 'tying' the front and rear panels together.

[richluvsound]

the dog brace is screwed to the vertical brace of the rear panel

[JBLOG]

Thanks!

Love that veneer!

- there are no screws through the baffle.

- there are screws through the back. I have not opened to look, but they are positioned about where I would expect the bracing to be. They are inset 2-3/4" from the outer edge of the cabinet. There is only one screw for each brace on each side (four total).

......So I have questions......
I'm looking at Bo's pictures & it appears that the baffle is 1" plywood. The bracing in the back of the cabinet appears to be particle board/mdf??
Is the cabinet itself built in mdf?? Can't tell by the pictures with the insulation inside.
Great pics & great thread!
