[burbeck]

hi all,
the above says it all, this one has strange fault cuts out the in again? after 10 mins

Hello Burbeck,

did you ever get your schematic ?

if so from where and if not did you resolve the problem ?

I have what sounds like the same problem on the Intek, suddenly both channels are lost from all inputs, problem seems to rectify itself if the equipment is left for days sometimes weeks. Obviously this is not a practical solution.

hello forum,

this is another post, you seem to require me to post despite the fact that I have nowt more to say

 

[burbeck]

hi there,
yes i have got a schematic and i did sort out the this amp.
it was a thermistor faulty on the pcb
the schematic that i have is a very bad copy but you are welcome to it please email

hi burbeck,
I have the same fault in my intek. Cann you send me the schematic to find this thermistor?
with the best regards

Hello,

Could you send me this schematic too? My email is maziere_jeanyves@yahoo.fr

Thanx a lot

 

[burbeck]

done

Hi Burbeck,
the Thermistor I have replace, but the Power transistors are to hot (in approx 20 min) , also q602 and q409 to. I have replaced all this critical ZTX... transistors and their capacitors also 22µ. Power Transistors are OK and their Drivers to.
Do you or any from here have any suggestions?
thanks

hi hifi_wein

did the amp work at all before you changed components?

have you got the same problem withg both channels?

measure the Iq and offset voltage on both channels

this amp does run warm

 

[hifi_wien]

hi,
no amplifiers that had the same error even before the exchange of components, so the output voltages already agree it is only my opinion warm.Ich thought to myself that leads to off after about 20 minutes

 

[burbeck]

hi,
measure the Iq on both channels to see if they are roughly similar

this amplifier runs quite warm

I too would appreciate a schematic. I've just won one of these with whta sounds like a temp cutout issue...also msuspect same as you guy's.
Many thanks.

PS just found this board, looks really good. Most of my kit is Radford: Valve, Tranny and speakers. I also have collection of Rafrod test kit.

 

[burbeck]

hi
i will swap you for any piece of radford kit. esecially the test gear.


drop me your email address i will send you the schematic such as it is.

Hello

After a search it seem that this NTC thermistor for the Linn Intek are same than this one who have 25k ohm at room temp;

RL2006-13.3K-140-D1


You can find it there;
