RGB Amplifier Board Failure

[Orbital]

Hi All,

I've just noticed that my amplifier board has started to fail on my BD800 red tube I just wondered if anyone here has a spare one they wish to sell?

 

[Mad Mr H]

Contact MrKing, a member here, he has spare parts, europe based.

If you suspect the Output FET then you may be able to repair. The FET in question is still available from American sources including ebay last time I checked. Worth looking out for see this link for details.

If you decide to ditch the module I'll take it off you're hands and may have a go at the FET replacement to see what happens.

Hi Everyone,

Yes I've seen that site and how to replace the FET but I was having some difficulty sourcing the part. Has anyone got any links?

How much do the boards go for? Roland sent me a replacement one for my green tube a few years back and I can't for the life of me remember how much it was!

 

[mrking]

Yep I've got loads of these.
Dunno what they should cost. £60 perhaps?

Surely it's only a transistor - less than a fiver unless you're being ripped off!

 

[Mad Mr H]

Mr King would have meant a tested working full card NOT just the single component.

Not everyone is good with a soldering iron, more damage than good can be caused with an iron in the wrong hands.....

I think I'll go with replacing the transistor. With around 10 successful chipped xbox's of mine knocking around I think I'll be ok I just need to find the part Any ideas where to start looking?

 

[cosaw]

Any ideas where to start looking?

I'll have a look round on the net tonight. I know I found some last time via ebay from the US but other electronics distributors seem to list them also - off memory.

Thanks cosaw,

I did find THIS place last night which when you do a search for the part number "2SK511" under semiconductors comes back with the relevant part. I sent them an email to see if they actually have in stock, will wait and see.

Dave,

Luckily one of the few private messages I've kept. A member called Stargatefour managed to get hold of some from this ebay seller:

http://stores.ebay.com/Bluestar-International-Components_W0QQssPageNameZviQ3asibQ3astoreviewQQtZkm

He has non advertised at the moment but its probably worth dropping him a line via email.

I'll edit this post to add any more sources if and when I find them so you can check back. The question is which links are relavant and up to date?

Shows 2 in stock here. Read minimum order - I think it suggests £10 for Non-business customers so the two left will take you over the £10:
http://www.mark5.co.uk/proddetail.php?prod=2SK511

A while back but Curt was offering them it seems:

Again don't know if they've got stock but it sounds like they may take small orders from hobyists:
http://www.cpcares.com/transistors/2SK511.html

Another but not sure if bulk orders plus there is a 4 on the end of the part number:
http://www.4starelectronics.com/part_search/PartSearchResults.aspx

You could try these guys: http://www.cricklewoodelectronics.com/Cricklewood/customer/home.php

They don't have any listed at the mo but maybe they could source them. I've had success with obsolete trannys from here - if you know what I'm saying!?

 

[Orbital]

Cheers cosaw your a gent mate I'll make some enquiries and see whats what.

 

[Orbital]

Well I got hold of the transistor in the end and my red tube is now fighting fit. Trouble is my green tube has started doing exactly the same thing It never ends!

 

[cosaw]

Yay!

Did you not buy 3 or 4? Or were they expensive? Which source did you use in the end?

 

[Orbital]

I could only find the one cosaw. I used the place thats in my link above. I'll have to start another search with the looks of it.

 

[cosaw]

Theres bound to be more out there - just a little more work!

Hi all,

New here, but not so new to CRT PJs and glad to help before I post any of my own problems

If the part number is 2sk511, theres a place called Donberg Electronics that seems to sell them. Theyre ireland based, but ive used them for parts before and theyve come through OK. Selling them for just over 10 euros each. Id post the direct link but im not sure a new user can do that.

Hope this helps,
Jas.

 

[cosaw]

Nice one Jas. Think you should be able to post the link even if you only copy and paste it and its not clickable. Might have a google for the place anyway!

 

[Mad Mr H]

http://www.donberg.ie/search/search.pl?query=2sk511&maxlines=100&wordflag=and&group=&page=0

there is the link, PLEASE CHECK this is the right part number I have only taken the above post details and created the link.

 

[cosaw]

Smashin - looks like the one to me!

 

[Orbital]

Thanks everyone!

Looks like it's soldering iron time again!

 

[jasonf01]

Glad to be able to help for a change.

Donberg seem to do a lot of weird stuff that nobody else stocks, handy company to have around at times like these.

Jas.
