EQP-1A3 Service issues ;-)

[13engrsapper]

So this just came in for power supply recapping and general service. The first and most obvious problem to me is that everything is upside down, even the back.

Now I thought about it long and hard - perhaps I could machine a new faceplate which faced right side up... etc. But as we wanted to keep as much of it original vintage as possible here is what I plan on trying... carefully.

I am first going to remove everything from the faceplate and carefully set that aside. Then I can remove everything from the back of the unit desolder all the connections, remove the back plate, and then take all of the components out of the chassis. I will mark each component as to which side was up that should down and hopefully I can reorient them all during reassembly. I am just going to use a magic marker on the power cord with some white gaff to make which is up or down. I don't want to have to make a new vintage cord; that really takes some patience.

At that point, I can flip the chassis 180 degrees to the earths surface, and begin carefully reassembling the unit right side up. If I put I all back correctly, it should be right side up when we are done.

I really hope this one come out, the last one came out all sideways.

PS: I was going to save this until April 1st... but what the heck.

Good luck ! I wouln't try that on such an expensive piece of gear ... but your commitment is beautiful !

Or use a table saw to slice it into 500 series.

 

[13engrsapper]

that's how I messed the last one up

 

[noizetoys]

What kind of blade did you use? Makes all the difference.

Also, make sure you are cutting WITH the grain!

 

[JMan]

I notice that the faceplate is brushed aluminum. How do you plan to reverse the brushstrokes?

Is this an April fools joke, Hope you know it's not April.

Kinda said that in the postscript.

 

[13engrsapper]

It's nice to rest the brain and laugh.

 

[noizetoys]

Wait, this ISN'T a joke? Good thing to know.

Guess you won't be needing this Audiophile saw for the front panel....

Oh, well...

 

[13engrsapper]

if you have a calibrated one, it may help. I am also trying to find a way to shrink the entire audio spectrum to just a few hertz bandwidth. That should make it easier to use.

May I suggest you sell it to an Aussie and buy a correct one?

 

[13engrsapper]

Lol, I guess it was made for them..

 

[noizetoys]

Oh, so he has the Southern Hemisphere version. That makes sense.

 

[13engrsapper]

If I only had an Australian friend to give it to

By restricting the BW to 10kHz, you could fit it in a 9.5" rack.

That made my day, thanks!

 

[noizetoys]

You can fit anything in a 9.5" rack....if you push hard enough!

That is my biz partners thought. He also likes durability testing things here by throwing them from his second floor office onto the concrete floor below- my floor. That is how he tested our stomp boxes back when we made them. To be fair, it has worked out. We both came up mostly on the road, supporting bands. So our gear tends to be built with durability in mind, along with ease of service. Features tend to be limited to what you really need, along with your ears.

I guess with limited bandwidth, I could squeeze two into the space it normally needs for one. Probably can save a ton of money racking them up, by just gaff taping them together.

Real DIY'ers don't tape! They WELD! Same for soldering!
