fleabag

When i needed to shield a bass pre cavity many moons ago, i found copper foil , with sticky backing, on a roll, just like seloptape. Mind you, it was quite thin, which may not be your bag. Very convenient though

Ah of course - fair play. Nicer looking logo allround, anways

Its probably similar. Its called Knauf but it doesnt seem itchy at all

What was wrong with leaving the Harley Benton decal on it ?

Its a pity ya cant buy this stuff by the square metre. 7.28 Metre roll and did nearly the whole cab with a square metre. Only 6.28 metres left

Cheers MBA I'm liking it. I thought i'd end up with a boxy bonfire cab, but the opposite is true. I've bought meself a pint

Cheers HRH Yep, bottom end is where i roll. And so does this cab. It doesnt buzz or vibrate, and with the crackle gone, we have a winner ! Buy yourself a pint and i'll send Speckled Jim over with a £5 note

TVM Its getting a workout as i've got Art Garfunkel , John Martyn , Vaya Con Dios and other tracks to learn

Bingo - tried it outside cab first No scratchy, no crackly. What is all that about then ? I can only think that the basket was slightly twisted due to uneven torquing of retaining bolts. But whatever it was, its gone. Cab sounds very clean, with a hint of warm, even down to big flappy E on a EUB. No farty, no boomy. Its probably a 50 Lb + cab, but i can live with that.

Throw 'em in the bin. 5+ are the spawn of the devil

Ok, i'll stuff it back in the cab, but rotate it 180 degrees, and then do a proper torque sequence as mr spondon noted and see how things go

You've been a great help

PS chaps - thanks to all for chipping in quickly at this late hour. Appreciated muchly

Right chaps - did the cup method, couldn't hear much, maybe a slight whoosh, but nothing like the scraping heard before. Took the driver out, checked for obvious splits / damage / damage to thin coil wires, and all ok. Tried the cup method again and .... silence ??

I'll whip the driver out next and check those. I know a new driver from BA is about £118 , but for a repair, when you factor in postage each way for a 17 LB + driver , then repairs, i cannot see this as being economical

Thanks chaps - will have another go using the cup method. I did a bit of googling too, and someone mentioned that a possibility was torquing the driver mount bolts in an ueven fashion, slightly warping the basket. Any ideas on that ?

A lot of this is out of my comfort zone, so maybe another driver is the only way

The 6 o'clock thing - If you look at the cab face on, then i was pressing at several points on what could be called ' the clock face ' EG I pressed the driver at the top as you're looking at it - say 12 o'clock - and then at other points on a so called clock face , 3 , 6 , 9 So, the scraping noise was at the bottom of the driver at about the 6 o'clock position Is the magnet accesible to re-position ? What is the coating on the copper wire - can that be re-coated ? The Fane driver was bought from someone on here, and it never saw a gig with me, because i was either gigging my 2 Beyma 2x10 cabs or my 2 markbass cabs, and i've never dropped it either. I live in a flat, with people below me, so its never been louder than practice volume when it was in the massive Peavey cab. So someone has sold me a duff speaker

Just had a look at the speakon connection wiring - its fine Then did the silent push on the driver, no amp I thought it was silent, till i got to about 6 o'clock position, and there's a loud scraping. No scraping sound anywhere else ( 9 o'clock - 12 , or 3 ) What do you think that is then Stevie ? Only making a scraping noise at 6 - its not a whisper either

I've hooked up the amp to one of my Beyma 2x10's, and using the same speakon cables, and guitar leads, the crackle has gone. I think the only conclusion then, is that the problem is the Fane driver. One thing i need to check is both speakon screw terminals to make sure the wiring is solid, but i'm doubtful that's the problem

Havent dismantled and de-soldered the driver from the cab , so i may need to do this at some point

I did what they tried in that AV thread already - see my post above

The amp is about 6 weeks old - i guess it still could be that, but i doubt it
