Kuartlotron Error Correcting Super Buffer

[keith_correa]

There is one mistake. Instead of 220 Volts i wrote 200 V, but that will be fine for me after all i will be using this Buffer. but yes for next time i will cross check the matter 2 times before printing it.

What does "0 dB" at that position indicate?

Just looking into Grounded Grid Pre Amplifier.

Anything from Troels gravesen should be excellent.

What has Troels got to do with the Grounded Grid Pre-amp?

Actually I found one design from Troels gravesen site. That's all.

I'm getting more and more confused. I think I'm misinterpreting/misunderstanding what you wrote or intended to write. Are you saying that Troels has a GG design up on this website? Where? I just find a page on his website describing some capacitor changes that he did to the GG that he owned.

Don't confuse yourself. Here's the link for reference.

Maybe I've misinterpreted this in the first place. I hope this will not raise any more confusion or controversy.

That is the page where he's described some cap mods that he did for the GG.

Thanks for the clarification.

I Saw that printing on a Cross-Over of DAS audio. They have Provided a Volume Control to Adjust the Volume of SUB. On that Volume Control in Center Position they have Printed 0 dB. Nothing Much more about it.. its just for Aesthetic look nothing else.

that same '0 dB' appears on equalizers too. IMO its like no change in input and you can reduce or boost from that default input level either in +/-6db steps.
BTW, I did not read earlier posts - how its getting into this Kuartlotron buffer?

Some More Photos of Enclosure of this Buffer..

Front & Back Plate with Connectors and Sockets fitted.

Inside Frame of Enclosure made from MDF & colored in Black Paint (Grain Texture)

Top and Bottom Plates are in Power Coating Process. I May get them by tomorrow. I Will upload more images after the Enclosure is Completely Assembled.

Good work. RCA color codes red - right and white - left.

Thank you for your comment Omishra Sir. I will rotate it to correct side.

 

[saikatbiswas82]

Looking very nice. Waiting to see the final outcome.

Some More Photos of Assembly

Front Panel is yet to be assembled. Knob for Volume Control is in Machining Process. Once received the Enclosure will be Closed and will upload the Final Photos. Till then testing is Done with Crescendo ME Amplifier and my testing Speakers.

Results .... :yahoo: Just Awesome.. (For me at least)

Testing Speakers are Not that Good but still they sound like PRO. Will plan to make Bookshelf Speaker later on when my pockets allow me to do so ... lol.

Today got the knob and Legs for Enclosure. These are machined from Alluminium ROD.

I am thinking to Black Anodize it, but i am afraid if someone here locally can do such a small quantity.

I think on a black enclosure, the aluminum knobs will look more premium than black anodized knobs. IMHO.

is the separator in the middle for mechanical reasons, electrically it does nothing..

I have seen Joshua's build photos he has used 2 Plates to isolate the Buffer Circuit from signals generated by Power Supply. I Thought i can use MDF for same reason.

I had Discussed with Mr. Shaan about this, he also suggested me to use Metal plates instead of wood. But I thought to give it a try by using MDF partition.

Can you please tell more in this matter. This MDF is 12 mm thick, is it not sufficient to act as a barrier to block the signals from power supply? OR the Properties of wood are not suitable to block the electrical signals.

If this doesn't work then, I to have provision to screw MS Plates on both the sides of this MDF partition.
