Any chance of getting the Intek schematic from some genteleman on here? :)

I have exactly the same problem as described by tiefbassuebertrager on page three:

This causes extremly cracking while rotate the volume control, even by use of a new variable resistor therefore



PS-II If you create an ultimate "outdoor" power supply with low internal resistance, the sonic quality of this integrated amp is superb

Tempting idea! I might be stupid enough to try...... :D

There is also the schematic from those section (post #29 pdf attachment).
On the last page of this pdf you will find the necessary modification steps.

BTW - I have heard, that Linn launches all schematics on demand from those models of their audio components, where Linn itself don't longer offer service, repair and maintenance.
Thus you will get the manuals from Linn.

Thank you for your help Andreas, I followed your instructions successfully! The left channel still has a very faint crackle when I adjust levels, but it's hardly perceivable. :)

Squeezing the big capacitors in required some creative thinking though :D

I ended up de-soldering one leg of R45/R145, and glued the capacitors to the heat sink with hot glue. The capacitors legs were just the right size to be directly soldered to the previously desoldered legs of R45/R145. :cool:

Forgot to take pictures..... :mad:

I checked your website, you have some nice stuff there and seem to be doing interesting projects! Found some useful links, so thank you again!:)

I thought you might appreciate a jazz link: Home :: HGBS Studio

It's the homepage of the re-animated HGBS recording studio, better known as SABA/MPS. They are releasing music again, and also have a huge backstock of old SABA/MPS vinyl. The ultra-rare stuff has already been sold, but they still have a lot of fantastic albums in mint NOS condition. Free guided tours are also possible on appointment.

I wish you a pleasant holiday season, merry christmas and a happy new year! Greetings to the Hunsrück,

Bob
:hohoho:
 
check out the attachment. This schematic I had create some years ago.

For better resolution the use of the "POWERTEK" schematic is helpful (found by electrotanya) - go to the attachment. Maybe one of the members know, where I can get a high resolution schematic version of the "INTEK" - thanks for advices.

I have get a Linn Intek with extremly crackling on both channels while turning the attenuator knob. Cleaning don't remove this annoying noise.
in post #29 there is a PDF attachment for the MM/MC RIAA section.

On last page of PDF is to find the schematic of the line preamp section (NE5532 is in use) include volume control and include the associated modification hints.
Additional I removed the jFET's for MUTE control
After performing this steps the amplifier works now without the above mentioned unwanted occurring crackling. Check also out the first five attached images

More pics. The kind of mounting requires a complete disassembly of this integrated amplifier to get to the bottom (solder side) of the PCB.
On the first image you will find a layer of fat on the PCB surface - this means, the amplifier was near a cooker in the kitchen at the previous owner.

in this attachment there are discover interesting additional steps to improve soldering and contact reliability of cinch-Sockets and the big capacitors behind the rectifier.
