The 1M5 resistor was originally 1M. I'm not sure why one would change that :?: unless the modder empirically determined that the change in voltage made for more clean headroom. Thanks Mark, yes the 1M5 was added for more clean headroom as there was a distorted sine wave being produced with the 1M i...

Thought I would give you a quick update guys. I received the amp back off my local tech over a week ago now and I have been playing it through a 2 x 12 WEM loaded with the Purple fanes. (damned nice it sounds too!) Still lots to do in terms of recap etc but I thought you might like to see a mod that...

Today = Heat shield cleaned. Valve cans cleaned. Purples loaded into WEM and plastic magnet cap reglued. Grille cloth steamed with a modified Black & Decker wall paper stripper.

Clean photos will be uploaded here.

Ha! Ok... ok... I hear you both. I will leave the insides and the smokey tone well alone.. ;-) In the great scheme of things I know this isn't important... but I would like to buy the correct replacement carry handle, two chicken head knobs, chassis securing bolts and a replacement rear lower panel....

Thanks teethdream. The Tolex I can hopefully clean up without too much effort and I have some suggestions to help clean off the grille cloth but I could do with some advice regarding cleaning of the internal wiring and components please guys. After many years of being in a smokey environment everyth...

Will do Dave. :-) It's been stripped back to a bare shell at the moment. Drivers have been cleaned very gently and I have a small hole in one of them that needs a repair before I test them. The whole cab including the grille cloth needs a good clean and some glue repair to the Tolex. ie... Lots of c...

Yes, its a great shame about the valves... But some you win and some you lose I suppose. :( Its on the bench of my local tech at the moment to see how safe it actually is.... I would not have dreamt of switching it on. (If the transformer looks scary to you Mark, can you imagine what it looked like ...

Hi guys, Managed to acquire this yesterday.. Needs a bit of TLC. (understatement... :D ) Lots of questions coming probably regarding the missing pieces etc. Loads of pics in the two links below. http://s72.photobucket.com/user/philm0l/slideshow/combo http://s72.photobucket.com/user/philm0l/slideshow...

Thanks Doc.

I have a pair of 12" Fane's in my Roost 50w combo. Both have metal domes are marked 16ohm, 12570, 47/76 and both are dated 1977 according to the frame markings. What is the likelihood of these being rated higher than 25 / 30w please gents? http://s1091.photobucket.com/user/molissy1/slideshow/Fane

Great stuff. Thanks dude. (again.. )

Hi, sorry to drag up such an old thread guys, but can I ask how relevant this process is today please?

I am only asking as I have a Crescendo with two tears in the cone and wondered if I could still use this guide to help repair it?

Many thanks.

Seen it, watching it, expecting it to go for peanuts....

Hmm, well, one has water damage so will need some sort of repair before use it and I am not sure what to try the other one in TBH...Maybe a separate cab or a replacement for the large RA50??? Or use the ext speaker connection on the 50 to a seperate cab??? Bought on a complete whim and I am now lost...

Hello gents, hope everyone is well. :wink: I managed to buy these the other day and now they have been delivered I am not sure if they can be used for guitar or not? Any advice would be greatly appreciated please. (thank you in advance) http://i72.photobucket.com/albums/i193/philm0l/fane/IMG_0010_zp...
