400 Series II thick heat sinks (8 fin)

[WOPL Sniffer]

Anybody seen this??
This 400 II has really thick heat sinks and the nylon shoulder washers don't go through the chassis and sinks. Then the outputs won't reach the QFP plugs in the back plane... My first 400!!!!

This pic shows how shy the shoulder washers are of going all the way through.

Now I've had em where they dont come all the way out, have ya stabbed an output.?

 

[WOPL Sniffer]

An output barely pushes the QFP

the heat sink is .17 inches thick. I dont know how thick they are supposed to be. The chassis is the same thickness as a 700-

Heatsink shouldbe.125 IIRC...

 

[WOPL Sniffer]

These are WAY thicker. The leads barely clear and the bolts are barely through

The protrusion of the nylon shoulder washer is only .14 and my heat sink is .172 by itself

I emailed Joe to see if he's seen it before but if you haven't, he probably hasn't either

 

[WOPL Sniffer]

damn goofy assed 400.... Figures that I would run into issues on the first one I decided to WOPL instead of launching into the lake (which is froze over)...

You have my kind of luck….nothing goes exactly as planned and always requires a plan B…..always.

 

[WOPL Sniffer]

even the original plastic sockets were too short. These heat sinks must be machined incorrectly

 

[WOPL Sniffer]

Pissed me off. Thought I'd finally have an amp besides Ronnies which will be leaving in a day or two. I have a 700B but no back planes and control board, and a 400 Series II with all the parts but it won't fit together......

 

[WOPL Sniffer]

fuck it, I'm drinking

 

[WOPL Sniffer]

I measured a 700B heat sink and it's .13...... this 400 sink is .17

guess I can't bitch since the 400 II was given to me but I wish I would have discovered this BEFORE I spent a shitload of money on parts.

JOE!!!!!! I need a new 400 II Chassis and sinks.....

Got a belt sander? I know it’s not ideal but sand down the back side and rattle can it, it can’t be seen and I wouldn’t think it would matter electrically?

I got sugar and NO Cool-Aid, Cereal and NO milk, a cigarette and no lighter, weed and no pipe.........................

I'll get drunk and rub it on the frozen cement in the garage till it's thinner. Or, if it ever warms up I can take it to my CNC bro

Well shit…..guess you don’t have a paddle for the creek your in either.

 

[WOPL Sniffer]

I could use longer screws and just solder the outputs in like the old days.

It's 10 below, the creek is frozen

10 below…..fuck that, I’d be drinking too.
