Is there an explanation why to pick 1uF ? Any value between  .22 and 1uF is good, and higher = better ?

Generally in dc coupling situations right after the signal path a bigger micro farad coupling gives more bass. The lower the rating i.e less than 0.1uf you'd get more clarity with vocals but also brighter sounding ambient. You can't exactly drop the biggest rating cap as well.

Yes with polypropylene caps i.e MKP's, PIO's etc they get expensive fast as you increase the rating as does its size.

Those are coupling caps for the driver tubes. There is no capacitors in the signal path, that's the beauty of the design.

OK DefQon, so as usual, it's a question of balance.

Driver tubes or not they still affect the sound more or less as the end application is still the same and the ground coupling rule still applies, if it were for AC coupling then you would not get any difference in the sound department.

 

If there were no given differences in changing coupling caps David would be smart enough to not include this as an upgrade option. He knows these circuits better than any of us here unless you get another engineer to verify the circuit, the schematics can be improved is what I've been told when I had the hum on mine removed on SE operations.

I agree but the effect is likely to be very subtle and I am not convinced changing their value would affect bass as they are not in the signal path. Better caps would likely provide better transients and a smoother sound.

What's the purpose of adding a small cap parallel to the main one ?

post #1028 of 2360

I've selected some contenders, need to check if they fit the case or not... and thus which value to choose.

I'm putting the order soon ! :popcorn:

Just ordered the MKVI+ and payed for it now :D Looking forward to its arrival!!

post #1030 of 2360

By the way, what is up with the old www.littledot.net ? Can you reach their web?

post #1031 of 2360

No the page is down but will come up again later on this week :)

I would love to see a picture of the inside.

Yes, the fans were not fitted to my amplifier, not enough room.

 

I am using an external fan mounted in the shelf under the amplifier, so I can run a larger fan and the power supply for the fan is not part of the amplifier circuit, so it eliminates electrical noise from the fan.

Thanks. Looks impressive. I found the amp run a lot cooler when using 5998 or 7332 tubes so fans are redundant.

Anyone have any experience using the MK VIII SE with the HD800 (and also Grado RS2, Ultrasone Pro900 or Ed8)?

 

I found this on ebay and it appears that they a located here in Hong Kong. I am thinking about checking to see if they allow local pick up.

I have finally returned to Shanghai with my new tubes I bought in the USA. Sound is amazing. Volume is higher, wider more detailed soundstage, etc... If you are using stock tubes, please change ASAP! wink.gif

One NOOB question... With the old tubes, the left and right meters were between 60-70 mA, with the new tubes they are both at 35 mA. Is this just dependent on the tubes I used? Why the lower number equals louder sound?

By the way I am using two Tung-Sol 6SU7GTY and four Western Electric 421A tubes now.

Regards,

Karl
