Marshall power switch problem

[dudewheresmybass]

I'm having a problem with the power switch on my Marshall DBS 7400 head.
There seems to be an issue getting the switch to work consistently.
Marshall have now informed me that they can not supply me with the parts for health and safety reasons.

Can anyone help me source a replacement?
The switch looks like this

The side of the switch has markings which include
250v~ac t100
10 (6)a
250vac 12a

Cheers guys

You could try spiratronics bits box and even eBay. Just check the mm dimensions of the switch to get a good replacement.

Google image search is really useful for finding a match.

It might not have the same markings on it but need same number of connections

Cheers mate.
It's 20.5 mm wide and 14 mm high

After speaking to my local electrical supplier, I looked on the rs website.
I entered what looked like a part number, I found the part I was looking for. £1.39 with free next day delivery plus vat if ordered online 😀
For future reference the rs number is 2284581

I'm surprised that they'd sell you the [color=#282828][font=helvetica, arial, sans-serif]parts, for health and safety reasons. [/font][/color]

[dudewheresmybass]

That's right. Marshall no longer supply parts to the public.
I would have to use one of their recommended repairers. Cue bill of £30-£40+ for something I can easily do my self!!!

Typical - just another means to squeeze more money out of the working musician. Yes, it sounds like you got the right replacement part. Be careful with the soldering as sometimes other parts are in critical proximity. Good luck with the installation.

[dudewheresmybass]

No soldering at all. Spade connectors ftw!
It took a grand total of 2 mins to install the new switch, and everything powers up perfectly, with none of the previous issues

[Dad3353]

OK, now you can go for a job on the assembly line building Marshalls..!

[dudewheresmybass]

I'd have to move abroad though

Something goes wrong, someone gets a scrached hand, fire, shock, dies. Cue no win no fee lawyers, £30,000 or £40,000. Cant blame Marshall can you ?

Lucky that the [color=#282828][font=helvetica, arial, sans-serif] [/font][/color][font=helvetica, arial, sans-serif][color=#282828]local electrical supplier was willing to chance his arm, then, eh..? What next..? Refusal to sell eggs in case of salmonella..? No more milk available for fear of tuberculosis, or getting one's head stuck in the carton..? Unable to buy a lettuce to stop anyone choking on a soggy leaf..? I'm quite OK with H & S; there are exaggerations sometimes, though. Maybe Marshall shouldn't sell cabs at all, in case they fall on someone..? Tosh, I say. [/color][/font]

Might be that the electrical wholesaler is selling a generic switch, but Marshall are selling a specific replacement part for equipment with design specs.

Marshall get them for £1.39 from RS or Farnell, most probably. It's a standard switch, looks like the one on my 20 year old Fender combo!

Marshall probably get them from the same place RS or Farnell do, but if they sell them its as a spare part for an amp. RS or Farnell sell them as a switch, and afaik RS at least will only deal with bona fide trade customers, who should know what they are doing when they choose the one they need and fit it.

[dudewheresmybass]

The switch I bought from rs is exactly the same as the one I removed from the amp.
Same part number

[BILL POSTERS]

That will be the switch manufacturers number. Marshal dont make them they buy them in. Its a generic part.

[planer]

Sounds like a good fix to me. Profit-related decision by Marshall I'd bet. Good for you finding the proper part from another source.

This was once the case for RS and Farnell. I think the OP got the part from RS. Farnell will now sell to joe public, I have a Farnell account, only need a credit card to set up. Got some pots, chips, Neutrik jacks and caps from them. Just be carefull you check you are ordering UK stock and not US stock, which carries a big shipping charge.

[dudewheresmybass]

As a self employed musician/ teacher I have a business name, so I had no problems ordering from rs. I also have a Cpc account too. I've had it around 6 years

[BILL POSTERS]

I been dealing with RS since they were called Radiospares, the first trade account I ever had. Expensive, but generally better quality than the cheaper ones.

Even a few years ago you needed a trade account and a rep had to call on you a couple of times a year

[pfretrock]

I also remember Radiospares, even before they sold chips and they had a catalogue that was about 20 pages long. Also remember the rep's bad jokes.
