Thank you for the replacement mounting screws which I received today. The Superfly is now back in its original case.


Despite my doubts that I'd ever see them, a replacement set of shiny, straight mounting screws turned up in the post this morning. I guess if I ever have cause to take the chassis out of the case again I could use them to reassemble it.

Anyway, seems like a polite thank-you to Bruce is in order.

Zinky Superfly Blog - Part 72: Bite My Shiny Metal Chassis

Yes, this post is all about bending, although no parallels between BZ and a certain Futurama character apply.

Having established at least that the amp worked, I collected together some g-clamps, blocks of wood and other tools and applied myself to the task of bending the chassis back as much as possible to its original shape, the prime objectives being:

Zinky Superfly Blog - Part 71: First Test

I've powered it up and played it, as there wouldn't have been any point trying to straighten the chassis if it wasn't working to begin with. It seems OK.

There were no extra screws in the packaging. Nor was there the reverb pan that I sent you with the amp. I'm not particularly worried about the reverb pan as I bought a second one some time ago. However 6-32 screws of that length don't appear to be available in the UK, going by a 30 minute search on the 'net. Up to 2 inches, yes... over that, no. I would appreciate it if you could send me another set, otherwise I don't know where I'm going to get some from and wouldn't want to try fitting the bent ones?


I hooked the amp up to the original speakers and reverb pan in the original case and turned on the video camera and the Superfly, in that order.

After giving it time to warm up, I plugged a guitar in and took it off Standby.

In short, it worked pretty much as I distantly remembered it, including the reverb. Hooray. Now all I have to do is get hold of some new mounting screws and figure out how to bend the chassis back without causing more damage.

Progress on that front is described in part 72.

Yes, it is safe to operate.

However- I would absolutely use blocks to apply pressure on the chassis to bend it as close to square as you can get it.

Should be an extra set of mounting screws in there. If not, the screws are size 6-32, 3 1/2 inches in length.


Bruce's reply was factually helpful, although there was no extra set of mounting screws in the packaging, like there was no reverb pan.

It seemed sensible to try the amp out before making any attempt to bend the chassis back, to find out it if was working at this stage. What happened when I did? - see part 71.

Zinky Superfly Blog - Part 69: It Was Bound To Happen

Thank you for finding the time to ship the chassis. I received it yesterday evening (9 Feb) and my first opportunity to unpack it was a couple of hours ago.

You advised at an early stage of our correspondence that the chassis metalwork was not very stiff and the weight of the transformers was sufficient to cause damage should the amp be dropped on its upper face.

This is what must have happened in transit. Although the outer packaging showed no signs of impact, the chassis is deformed at one end. The fixing bolt at the displaced corner is quite bent. Please see the attached pictures.

The circuit board is also bent but does not appear to have cracked. So for today, just one question: do you think it is safe to power up and try?


On the evening of 9 February, the delivery was made - a day earlier than expected but I wasn't able to unpack it until a day later anyway. So the following evening I set up my camera to record the moment for posterity and opened it up.

One of the first things I noticed was that the reverb pan that I'd sent out was missing. Oh well, I had another one (see as far back as part 12).

With the packaging removed and taking a closer look, the next thing I could see was that the chassis was damaged. Oh great.
