i understand....and thank you for your advice...you dont know how much i appreciate it...
i do not have a chassis here....it is in the transport process....it is however in costa rica....
that is why i did not have the heat sink for the bias transistor...i must admit, that i missed that...
there is a 4 fin and and 8 fin on the way to me...the 8 fin is working...the 4 fin is parts....
i will know what i will do when i see what i got...
i was just trying to build what i could until my stuff arrives....
i got the new heats sinks and put them on the bias transistors in the kit....
and extended the legs....both test good...
i will need other stuff too....
i ordered an extra dcp board
and will need 1 or 2 light boards and cap kits at the least....
i can always just ask joe to drop in a couple of bias transistors when i order....
main thing is to make as much progress as possible....as my life has an expiration date....lol
thanks sooooo much....

bunch of rain last night...

the year in my scenerio is from may 1 to end of april....this is because of the rainy season....which starts in may....
as you can see....it is wet....lots of local flooding all over the country....but, it happens every year....people dont worry to much....

i think i will get busy looking up and cutting wire this morning....to finish up the back planes....i am sure those 2 400s will be here this week....
and i can make a few decisions....wish the new chassis of joes came with fins...lol
oh well, i will just deal with it as it pops up....

seems i made a mistake on the bias transistor and installed it prematurely....it was too short so i had to remount it....i did have some new p style heat sinks from a repair kit i bought a while back....they are now installed and check out just fine....will probably order a couple more from joe when i get the other cap kits and light boards....i did not have my other units to rob for the clamps....i just jumped the gun....which is typical for gene....lol

yes sir, i removed the 3405s ... put them back in the parts bag....
replaced with 2n5088s.....installed on board....
tested after installation to make sure i did not hurt them adding the legs back...

i will probably replace them when i get up my next order from you....when the others get here
so i can take total inventory....

thank you joe....i appreciated very much...

this is as advertised....a very high quality product....i know you are proud...
i sure would be....

when you get your New tester, you can test them and you will see the different between BCE .
So anything you Substitute to a different Part # Sometimes the transistor layout chances. (always good to check and know)
You should buy bunch from Mouser or Joe , their cheep.

Need a green B+ wire from the top right of the RHS backplane to feed the B+ terminal on the DCP. Also, if your going to feed the meters after the DCP relay, then remove the small red wires at "Out 1" beside the yellow wires at top center on the backplane.

And make the left channel white and the right one red as the wire list in the instructions indicate...
