Working on Nelson Pass First Watt

[GeorgeO]

The boss is Nilesh Vadhar, who is a director. They make one off pieces, with a short delivery period-depending on their load. Check their web site, I am sure their number is there-toroidal.com

ZTX550 Alternatives..

close alternative is 2N6728, BC series are of lower power, 500mW , where as ztx550 is 1watt..

You should have no problem. Look for my posts in that thread to see my heatsinks, also note the concern voiced about keeping the two halves at roughly the same temperature to avoid offset issues as the output node voltage has some correlation with the temperature of the output transistor.

Peter has a nice picture of a workable solution for the same.

I looked this up. I should say Peter Daniel's unfinished amps look like nice!
I will try to couple the heatsinks directly together. The top/bottom panels should do a bit of coupling too I think.

I talked to Salzer and he requires a Minimum order of 10.

Did u checked your self . I contacted them telling i needed 1 - 2 pieces , got a quote for 600Va trafo.

Some will give false info , be careful.

Hi Cap'n,

What speakers are you planning to use with the F5's? Also, what time-frame are you looking at for completion? Thanks!

Hi Cap'n,
What speakers are you planning to use with the F5's?
Hi Grubyhalo

I'm presently using speakers whose cabinets are designed by Viren using drivers from my old Kenwood speakers. I intend to use them for a while.

Upgrading speakers, umm.. I've not readdy decided either to go the single driver way or threee way towers which again would be DIY effort.

Also, what time-frame are you looking at for completion? Thanks!

Six months would be sufficient I guess. How is the progress with your project?

Reviving an old thread. How many guys have made the F5 here?

 

[gobble]

I am waiting for delivery of the F5 PCB since 6 months now

Sudhir has forgotten.

Oops, is that so?

I spoke to him yesterday and he said it is available

Hi Guys, any chance this kit is still available? Happy to pick up a stereo pair.

FM Aniket has designed a Class A/B amp, using Toshiba BJTs. The modules will be available at 75W/120W per channel. The modules will be provided with suitable heatsink. Let me know if you have interest.
