I too can't believe that all three are beyond repair, Anyway, the lids are aluminium, you sure your chain isn't being yanked? (As an Alfa owner one needs to define "corrosion"  ) |

It just seemed strange to me that a company that supplies parts for these amp's would right off 3 of them and not be able to do any repairs at all! I wonder how much those amps would be worth if broken up for parts? ie 6 modules @ 60 quid ect I think I'd be looking for a second opinion.

Never criticise another man until you've walked a mile in his shoes. Once you have, call him what you like, you're a mile away and you've got his shoes!

I make you absolutely right regarding getting a second opinion.

£116 for a module from them exchange Mmmm.
I was going to buy some knobs to replace the nasty thing someone had fitted to one of my amps they were £1 each and £3 each for postage and I seem to recall a minimum spend too (it was a year or so ago) They also told me the Electroluminescent panel's were not repairable/available but Steve managed to get mine going using led's works a treat if not better than the originals. |

I can't believe that someone would do that, I have heard stories about guitar amp repair shops swapping out all the mullards and filling them with Chinese nasties and swapping bits of instruments but never with someone who's been in the business for years. My dishonesty only stretches as far as telling customers that a repair has taken a couple of hours when in reality I've spent all day starring at the same circuit board but don't want to look like a numpty so I always find these stories distressing.
I am halfway through rebuilding one for Colin, the repair involved removing the circuit board from it's resin and repopulating the board. Not beyond repair by any means and not 600 sovs either. Do I remember correctly that "grumpy" said he had some NOS boards in one of his many sheds? I too would be interested in getting/giving a second opinion but am also intrigued by :

I hear your pain, my DM flywheel and clutch have just gone south.........The vibration finished off my top engine mounts, both ends....bugger. Back to point, which bit is suffering from metal maggot? I am sure, even with the UK's depleted manufacturing base, metal can be folded and painted/coated to match original by someone for reasonable chunks of wedge? I have had loads of "things" knocked up by metal factors for not a lot, for example, Brembo Two pot calipers, got the last genuine pots/seals in the UK, and then had a little local metal worker to knock me up the pad retaining springs, pins, and even bleed screws! Some alloy wheel centering rings too, and change from £80. Beautifully done in stainless and sprung stainless. Does smell a little whiffy..... |

Could have done with a bigger picture, but apart from a little discolouring on the transistors it doesn't look that bad to me! I've certainly seen a lot worse!

Well seeing that photo,if the repairer said " dead with nothing salvageable cause red rust took hold underneath" then in my opinion he is either incompetent,or is having a giraffe. |

It is very easy to jump to conclusions (in this case very easy) but that doesn't look too bad to me.
Question: Does burningbush look like a bitch? |

Interesting, MAJ are usually pretty on the ball with HH stuff but it's always worth getting a second opinion. Also worth checking out the MAJ website http://www.majelectronic.co.uk/ quite a funny read in places from a guy whe definitely says what he's thinking!
