Thanks for your prompt reply. I have tried them with the gain in high and low positions and get the same results either way =/ though the low gain is slightly better but still unlistenable as the distortion is so bad. I guess I will just have to use my d5000s with my portable setup instead.

You're most welcome.

I made an impedance matcher for when I want to run my 35 Ohm Ultrasone's from the LD. I get a bad hum in them, basically all I did was take a 1/4" plug and a 1/8" socket and wire up an adapter with a 150 ohm resistor in series with each channel. It removes the hum for me, not an ideal solution but doesn't harm anything either.

It might work for you as well and easy to wire up loosely to test.

That may be the best bet. I dont fancy buying a completely new amp for my low impedance headphones :D. Thanks again.

Or you can get a LD 1+.;)

LD 1+ pair well with my AKG QXXX and i used most of the driver tube for MK III.

And some tube may sound nice in MK III but not with 1+ or vice versa.

I've spent so much over the last few months on tubes ,amplifiers and cables. Not sure I could justify spending even more on a new amplifier haha :D

post #6712 of 7574

Same here but for me at least i'am done spending $  for my LD's but BH CRACK is coming soon so that is another story for me.

post #6713 of 7574

You should follow Mordy's advice on buying tubes it works for me saved some $ set a budget per tube.

post #6714 of 7574

Sounds like its going to be fun :D. My aim for the future (a far distant future) is to eventually save for the la figaro 339. Sound wise its suppose to be terrific. It looks extremely well made and internally looks very clean.

post #6715 of 7574

Yup sure is a nice amp( la figaro 339)but for me i had a lot of fun making my own cables, adapters and chassis that is why i went with the CRACK and who knows maybe some day i will build my own tube amp.:biggrin:

post #6716 of 7574

Far more ambitious than I am. good luck to you. Hopefully the assembly will all go well. :)

post #6717 of 7574

Thanks! i think i need all the luck i can get.

You are welcome, hopefully it works for you as well. That La Figaro 339 is one gorgeous looking amp inside for sure!

Need a little help:

 

I am preparing a power supply for my coming 15A voltage regulator, and I wanted to use an old PS from a computer rated  +12V  14A,  -12V  0.8A

                                                                                                                                                                                      + 5V   25A,   -5VSB  2A

 

I plugged it into the wall outlet, but I am not able to measure any voltage at any of the 7 different plugs. The power cord to the PS has 115V - tried another PS and still no reading.

 

What am I doing wrong?

post #6720 of 7574
You're missing the power good signal there's usually a thin green wire roughly the middle of the connector and what you have to do short that to a black to get the power supply to actually turn on.

I'd send you a link but I'm actually in the car at the moment so Google is your friend. wink.gif
