wink Posted April 17, 2013 Report Share Posted April 17, 2013 Those plate through holes are a real problem. Need to check the continuity after re-soldering a component. I usually go from the component either side of the replaced one if the board has tracks on both sides of the board at that point. Quote Link to comment Share on other sites More sharing options...

Milosz Posted April 22, 2013 Report Share Posted April 22, 2013 I don't like the sound of this. Is this a design this is prone to blowing up with no provocation or are these problems due to assembly issues? "started after one of the K216's in the front end CCS had shorted through the insulation and a 3675 in the main CCS had also shorted." What insulation did it short through- the heatsink insulation pad? An insulating washer on the mounting screw? What kind did you use?

spritzer Posted April 22, 2013 Author Report Share Posted April 22, 2013 I was using steel screws and the heavy duty insulation. This is only at 250V but the K216's are a pain to fit with those insulation washers so that's probably why it shorted out. There was a nice melted puddle of insulation at the top of the K216 tab... The 3675 fail was at the PCB so sloppy soldering on my part or rather, sloppy desoldering. Never work on HV when you are tired... Quote Link to comment Share on other sites More sharing options...
Lil Knight Posted May 3, 2013 Report Share Posted May 3, 2013 (edited) Started working on the front panels for my second T2. Lots of fun ahead. Edited May 3, 2013 by Lil Knight Quote Link to comment Share on other sites More sharing options...

Lil Knight Posted May 4, 2013 Report Share Posted May 4, 2013 Need to spend more time working on the surface finish but I am quite happy with these raw panels. I opted for T6063 aluminum for a better finish. Quote Link to comment Share on other sites More sharing options...

Lil Knight Posted May 4, 2013 Report Share Posted May 4, 2013 I am still tweaking it a bit. Wanted to add a motorized potentiometer with remote control so I had to revise lots of things. Quote Link to comment Share on other sites More sharing options...

Who are you looking at for that. I'm having some issues with a four gang POT. Very nice work on the panels Edited May 4, 2013 by Kerry Quote Link to comment Share on other sites More sharing options...

luvdunhill Posted June 3, 2013 Report Share Posted June 3, 2013 Why skimp on the ventilation? If I recall Kevin had a similar pattern and had to go back and add more holes. Quote Link to comment Share on other sites More sharing options...
Lil Knight Posted June 3, 2013 Report Share Posted June 3, 2013 There will be 2 venting columns on each of the remaining top-bottom panels. Regarding the amp's top, exactly how hot is it? I might try to add some holes around the tubes or even columns, if it's really necessary. Quote Link to comment Share on other sites More sharing options...
spritzer Posted June 3, 2013 Author Report Share Posted June 3, 2013 Let's put it this way, throw water on the amp and it evaporates quickly enough to not short out the circuit... Quote Link to comment Share on other sites More sharing options...
luvdunhill Posted June 3, 2013 Report Share Posted June 3, 2013 I might try to add some holes around the tubes or even columns, if it's really necessary. Um. That is my point. Kevin seemed to think so. Look at the pics in the thread. Venting isn't the issue. The goal is creating some thermal resistance around the tubes so the top plate doesnt just conduct all that heat and act as a giant heat spreader.

Nebby Posted June 4, 2013 Report Share Posted June 4, 2013 I thought that's how you get proper "liquid" sound out of an amp? Quote Link to comment Share on other sites More sharing options...
