Got my kit tonight and built it in a couple of hours. Amazing.
Ok it was bound to happen. More questions

The first one is in regards to the 22.k resister that is is in the RF position on the board. Is the resister in the RF position the resister that was previously mounted to the chip?

The second thing is about the available space for larger caps. Is there any gains to using larger caps?

And last but not least, before ordering this transformer. I am going for a 300VA, with 24V rails. The question is should I have it made with 117Vac or 120 Vac? The leads in my house move from 117 to 120 throughout the day. If I go with 117 do I risk blowing anything up?
With Rf resistor there are two mounting options: either directly on board in a spot marked Rf, or directly on a chip, as pictured here: http://www.diyaudio.com/forums/showt...427#post584427 With a Premium kit I would recommend the latter method.

As to large caps, it's really up to you, some people like them, some people don't. I only use small caps now and my impressions regarding different configurations have been posted here:

I would go with 117V rails and Plitrons are made with 115V rating. There is no risk of blowing anything.

I have already soldered the resister to the board and trimmed it Oh well life goes on. I ordered the transformer. Went with 300VA with 24V rails. I figure I will always be driving 8-6 Ohm speakers so 24V seemed to be a good compromise.
As for the caps, dam that is a HUGE topic. I am not all that surprised though. I will be sticking with the panasonics. I figure you have been at this for ten years and know MUCH more than I ever intend to know about these things.

I can still replace them for you if you want.

Just posting to say thank you Daniel for the very reasonably priced kit amp boards. i completed the kit a week ago with mostly premium parts and am in the process of burning it in.

Having owned many valve amplifiers and various iterations and tweaked versions of the T amp and the Charlize in the past, i must say i am mightily impressed with the sound. Totally unlike those T-amps which could sound cold and sterile. if i was listening blind i would not for one moment have dismissed it as not being a valve amplifier of sorts.Very neutral, tonally accurate with good bass, excellent timing and rhythm and dynamically all I could ask for in a sensitive speaker set up. Although the DIY speakers are also relatively new to me i am still struggling to find a distinguishing character to the sound from the amp, and that in my book is high praise indeed. i am waiting for the parts to build the F5 next which i am very excited about.

So thank you again Daniel for that and the Shigaclone the best transport i have ever used.

Thank you; your impressions are pretty much in line with the review posted on June 3rd, 2005 on my home page (Latest News section): http://audiosector.com/

I would go with a second picture for mounting rectifier boards.
