how do I pull Airline 90113-A chassis?

[profgalen]

I can get it loose and slide it back but transformer is keeping me from removing the chassis. Do I have to remove or loosen the transformer?

I did one of those about a month ago and yes, it was a pain in the ass do get out.
It took two of us about a half an hour the first time to figure out the sequence of rotating and pushing it down off that lip while prying the thing out, but it did come out without removing the transformer.
Actually I can't even tell you how to do it because it seemed like it was a little different every time I took it out and put it back in.
This was one of those, "let's do something with this amp" and a lot of custom tweaking, requiring it to come out and go back in a few times....
Eventually I was able do it in just a minute or two when I was tuning on it.
Next time I see one in here, it is an instant +1 hour X $$ labor bill before repairs!

Could you remember what some of those tweaks are? I'm assuming these are point to point amps. I really don't know much about working on amps but I bought this one cheap so I could learn.

That's actually quite a nice little amp. If it's similar to the model 62-9013 that I have -- and it looks like it is -- then it's basically Danelectro's version of a Fender Deluxe. I wouldn't change it much, if at all. Just get it working right.

Thanks for the advice. I think I'll leave it alone for now. It works great as is even with the original tube (RCA and Westinghouse). Very quite so I'm assuming the filter caps are still good.

I'm sure a lot of us have been scratching our heads about that tight fit. Pretty simple, though: As you slide the chassis back, first the leading edge of the chassis will tend to get caught at the cross brace of the cabinet. The perfect tool for dealing with this, and stage two, I found, was a 2" spackle knife- to keep the metal blade from scratching anything, I wrapped one layer of masking tape around it. I used it gently as a wedge, sliding it across that leading chassis edge until it's free, then, more importantly, the same technique works with both edges of the power transformer. In other words, you let the pressure of the transformer against the spackling knife open the cavity just enough to slip through- both the rounded edge of the transformer and then the squared off body required the knife (anything a couple inches wide, and fairly stout will serve as a slip/wedge). Once you've replaced those dried out caps and drifted resistors, and added a grounded cord you should have a monster- I saw it described as a Deluxe in a Cigar Box and that just about says it all. Hope this didn't come too late for your needs.
