Parts GB for X-BOSOZ (KARI's Boards)

Coulomb · 1st February 2006, 02:59 PM

I have started sorting the kits out and have most of the PSU kits bagged. I need to finish matching the IRF610 FETs before I can start / Finish bagging the Preamp kits.

There have been some part substitutions due to exact values not being available at the time I was purchasing the parts, Resistor values mostly. There are some lead issues as the holes on Kari's boards were too small for some of the parts, which required a bit of creativity when I assembled the prototype boards. I had to change the Rectifier Diodes as the holes were too small for the 4AMUR devices I originally purchased. The Ohmite and Dale power resistors require some work to mount in the boards and the ELNA high performance 1000uf 100V caps are a little larger DIA than expected so I had to stand them off the board a tad.

The PSU filter caps are not all the same, but I will try to ensure each member gets the same caps within their parts kits.

Wiring the R-Core transformer is a little tricky for best operation as it has 4 outputs of 0-18VAC, 3 for the Positive section and one for the negative section. Finding the right combination is critical to proper operation.

This is all I have time for today, as I am posting from work. Please do not expect speedy replies to any posts you make in this thread, and please try to keep your posts cordial.

I understand there is a lot of resentment from more than a few members. Abandoning the Forum for 6 months was not an act with malicious intent on my part, and I do not wish to speak about it openly.

I also wish the Moderators could purge all the really awful rhetoric I have seen published about me while I was absent, deserved or not.

Regards

Anthony

Welcome back Anthony!
I´m really happy to hear from you again. I hope everything has turned to good account for you.

As far as it concerns me take the time you need to sort things out. An update every now and then would be great though.

Whew! Was genuinely worried about you. Best wishes (I'm assuming everything is not remotely sorted out yet).

Take it easy.

(wow, has it really been six months already?)
