Audiolab 8000A (serial number with 'F')



The Audiolab 8000A's with the alphabet 'F' in the serial number were the last production batch before Audiolab was sold to Tag McLaren.

I was lucky enough to secure a unit from a seller who lived down the road!!!. After doing so, I sold my British made Audiolab 8000S (serial number with  'E') and 8000A (serial number with 'D').

The newer 8000A still sounded "a bit raw" and less polish than the higher end units in my collection. Hence I decided to recap the unit using better quality parts, as well as performing some minor tweaking along the way.

The following pix was taken after the work was done using OSCON, Wima, Panasonic FC and ECA, as well as silver mica's.

Before Wima's inserted into pre-amp section was substituted with silver mica's 


This is what's under the big ribbon cable - the pre-amp section.
After the four silver mica's were inserted


The left side (from front) casing of the unit runs warm as the phono section has it's own voltage regulators which uses the left side of the internal casing as heat sink. I attached two heatsinks to the side to help reduce heat levels.

Took the opportunity to capture a 30second video to show the results, using my basic digital camera. The video was captured in MOV format and has not been modified in any manner of form - direct from the digicam to the PC and uploaded to the blog.

Was quite impressed by the ability of the basic digicam, although my daughter says it does not do justice to the real setup.

  2. Hi SK,

    Sorry thought I mentioned it last time? I have a full set of the British 8000 series which included the 8000A.

  4. Hi there, I just posted on the DIYAUDIO some questions regarding some mods for the AUDIOLAB, yours seem to be the best inspiration for this. I made a few question directly to you, I'm pasting here, but would really thank you if you consider replying in the forum too.

    So here goes, why did you use those OSCONs in the pre-amp section and should I get much better sonic performance compared to the Silmic IIs?

    Why did you placed those four silver micas, and why didn't you replaced the EVOX for WIMAs in the preamp section too, like you did for the power section?

    Also, what are the values for the two OSCONs (I think) used in the power section? They seem much larger than the original RE2s.

  5. I will answer your queries in DIYAUDIO but advise yourself not to proceed with such matters until you have atleast done some basic electronics course. Otherwise you may be placing yourself in danger.

  7. My 8000A still remains a real "ear-opener" for new visitors. Seems to match well with my DIY OB.
