CA-3000 the hunt begins

Note to self… when reflowing around the feed thru " pins"… don't push the pin UP or down.. and don't ASSUME the solder connection on the other side will reflow perfectly.
I reflowed a bottom pin.. and pushed it up JUST a hair.. the connection on the OTHER side was cold as Alaska… clean , reflow….filter problem SLOVED.

We came we saw we did MORE

In and out of the fader board re capped which what I had in stock ( running outta parts ) was able to totally clean the rear fader element.. and got tricky with the front.. Now the volume control doesn't SUCK and it's about 97% there… a little bit of crunch at the very start… but it would be picking pepper outta fly doo-doo… the pre is starting to open up.. I think the best change is getting the black junk off the edge connector pins.. So it's all back together ( almost ) need to find some hard parts ( power switch, muting switch, green LED's ) more cal & cleaning and BOOM she's race ready….

THEN BA 3K the NEXT HUNT….

2 AM engineering

The power switch looked like it got the Bruce Lee 1 inch punch…
Mechanicals were TWEAKED.
The fingers that rock the 2 leafs had there back's snapped off.
and the top mount point off the switch was snapped in 2 pieces.
( GREAT )

So bending,cleaning,gluing and I think all the sub assemblies will work once the J&B dries.

Yesterday evening, I used a LITTLE crazy glue to hole the top bits back to the switch body… just now I filed & scraped so the epoxy could hold things better.

Have a tiny bead of J&B to hold the spring to the fingers just to make re assembly easier.

All contact points are clean ( er )…
So lets see if this works… the ONLY switch I was able to find was 132.00!
( and that was on SALE ) SHEESH

So on the BA-3000 front… I saw this on Ebay 161334997758 Canada EH?
Now tell me I'm crazy….. He will take $900 ( + 90 shipping ).
I think he's OUT OF HIS MIND.. tell me if I'm outta line here and that's market value these days…


Blown & chromed…... sounds good on my 64 Vette. Not my POWER AMP!!
 
A modified (OMG that front panel !!!) non-runner for that cost - seems too much to me.

Better 121353253595.

Oh yes that is much nicer but out of the " budget" … PLUS I wound be able to do " my " do to it…...
 
Power switch.. FAIL
I didn't notice the cracks in the gray piece ( rocker ) that holds in the fingers.. switch worked 2X SNAP… back to the drawing board…..Everything else held nicely though.. Grrrrrrr
After more thinking, soul searching & balancing the checkbook ( finding I made a 225 double entry ) I laid down & bought the E bay power switch….
1 switch down.. 1 to go…..

Yep I know what you mean, it even be an AK'er who did the work?

I have a job ahead of me re-doing a partially done recon on a B-2102 and C-2102 - and I know it will feel weird changing out the crap that's been put in. It probably won't make much difference - just my OCD kicking in ;)
 
John if it was an AK'er who re did it.. that would be fine...
But since retirement.. I can't be as LAVISH about luxury purchases...
PLUS
These are all projects to keep me " amused ".. since most of my close friends are still working for a living....
I did buy an AU 6600 CHEAP.... just to get re aquainted PLUS I MIGHT get it working and part it out There are some minor parts I need off it..... for an other project...
 
I hear you Mike, I'm not retired yet - I really have to get into that mindset, sooner or later. ;)

And now - back to normal your normal program... :D

Power switch mod CA-3000

SO CLOSE… but no cigar…YET

So in a DESPERATE attempt to resolve the power switch ISSUE..
I bought a power switch for a Sansui SC-1100 cassette…
In hopes to graft bits together and make FRANKEN-SWITCH…

With 10 minutes I was able to graft my OLD back to the new front.. YEAH!
The cassette is only a DPST switch with isn't QUITE right for the CA-3000

BUT my old back fit on PERFECTLY ( JB weld and all )

The is a center tang on the switch that needs to be bent up ( easy tweak ).
AND
There is a black plastic insert on the nose surrounding the shaft.. that pops out with out to much of a fight…


So I'm thinking I'm DONE… Ahhhh not so fast the hole pattern is inverted.
BUT all 4 holes are punched out on the CA-chassis…. YEAAAAAAA!

Slide in in the chassis… OH NO MR BILL… the hole pattern is off…

So I need to have a think on how to make an adaptor plate..
OR
give the front chassis a little bit of a grind ( NO MAN DON'T DO THAT! )


BUT IT"S REAL DAMN CLOSE…. and this MIGHT be an out for someone with an AU-9900-BA-2000-CA-3000 ( or similar ) that has a COMPLETELY broken switch..

Note here.. the contractors in the cassette switch looks like they would be good for 5-7 amps.. so this would need the SCR mod to boot on a power amp

But it's a way out of the mouse trap.. ( more to follow )

This could work

So here's some chicken scratch showing what needs to be done to fit this…
But if you have NO OTHER OPTION this wouldn't suck as a repair…

The angle of the switch in the OFF position wouldn't match by ~ 20 degrees…
Once you get the front panel on.. only a FEW would be the wiser..

The bottom pix is a trace of the front panel.. the Ol business card behind the front panel trick…So accuracy of measurements… file to fit...

Waiting to hook up with my welder buddy to see if I can fix ( extend ) the lever for the 3 position attenuate switch to left of the volume control...

I think you have to press the trigger good few seconds before, just to be sure. Better luck next time
 
I was the high bid with 12000 yen of margin with 1 sec to go.... Someone just wanted it MORE....Sigh now hurry up and wait....
 
Power switch in & working... going to try a graft on to the atten switch of an original good switch arm/ shaft and some thin aluminum to make a splint.... on the broken switch arm which is just missing the little tit on the end
