Logo plate with grid sought

[Krischu]

I'm being offered a Fender Twin reverb amp that is equipped with a pair of E120 spkrs.

One of the speakers has a missing logo plate thus the hole in the magnet is wide open - hope the magnet isn't housed by mice yet :)

(see http://people.freenet.de/paulka/images/twin002.jpg)

Are these square plates (with integrated grid) available from JBL as new spare parts or can someone serve me with a NOS piece?. I'm about to buy this amp.

Thanks.

And while being at it: In how far do E120s differ from D120F? Sure, magnets are different. (Ceramic vs. Alnico). Is the magnetic flux density the same?
Voice coils? Does the E120 have copper wound or aluminum wound VC?

[Krischu]

I wonder, why a relatively simple question remains unanswered for quite a long time, given that so many experts are lurking around here :). Strange.

Looks like that cover plate has a Fender logo on it - not sure where you'd find such a thing - even JBL badges are hard to come by once they have some age on them.

Oh - and about searching for info on E120s vs D120Fs ...

Heather,

thanks for the detailed reply. Actually I wasn't expecting to find a Fender logo plate from JBL sources - maybe my question was unprecise. Such a plate by JBL would be fine. Also a used one from canibalized speakers would help. Well, I will probably end up building something on my own with a piece of fly gauze.

Thanks for pointing me to google but the search results are too vague and I cannot find the answer to my questions about magnet strength and voice coil property. Simply a pointer to the datasheet of either speakers would be fine.

Many thanks, grumpy. I'm glad to know that the E120 has also an Aluminum VC. I will read on.


BTW, maybe I asked this already, I know a GRUMPY from the Hammond list, is this you?

I bought this amp now and the need is there for such a logo plate (with grid) be it JBL or Fender.

Can anyone help me?

[grumpy]

Nope. Hammond ... that thing with the clicky keys, right? ;)

(I've never seen just a "foilcal/screen" for sale as a separate item)

It looks like what we call a foilcal - just a metalized printed label thats held on with something like rubber cement/contact cement... So - why not just slap a chunk of Duct tape over the hole to keep out the mousies and flies - its not really seen by anyone anyway, right?

[grumpy]

voice coil cooling. If worried, window screen + epoxy.

Clicky keys, more or less, depends on the speaker you use :)

Regarding the foilcal: I wouldn't mind a JBL logo being on it. Doesn't have to be "Fender" (which wouldn't be available through JBL sources anyway). But I guess you mean that.

In case anyone finds a speaker on a dumpster, please think of me. Don't send me the whole magnet, just the aluminum plate - for weight and shipping cost reasons
;)
