i can't see the first pulldown resistor, the 22k CC soldered between the two 80uf sreies cap and the first 22uf.

why did you change it with a 10k one?

wonderful!!!

any one has some board pics to show?

do you know the HT voltages?

thanx a lot!!!

thanx gng04, have you got others pictures? especially for the two boards, many thanx. seeing on photos preamp is similar but not the same compared to the k60 one, on the 3rd gain stage i might have a 220k anode resistor, and the PI grid stopper seems to be a 100k and not a 220k like k60. the reservo...

no one have any information about K80 amp? i know that is a special ed. of komet amps, but nothing more. it is a K60 or K50 inspired? sure it have three 83's and two KT88, i'm searching on the web but i founded no internal pics at all. i've built one, with k60 circuit and oversized HT (like 560vdc o...

hi guys, do you know how many voltages are on the seconddary winding in a concorde PT? i know that in the komet one are 365-0-365Vac, are the same in the concorde and change only the ss rectifier? i doubt with it, because i think the 22k pull down res is to much high if the mains voltage remains the...

this definitely is the best boutique tube amps, and moooore, forum on this planet!!!! so Xits are some of the best sounding tube amps ever heared! these amps have amazing dynamic, incredible tone....WOW!!! Xits x50 model...lovin' it from the first two notes. :oops: i'm sorry Bob but there are no bes...

wich preamp did you take for your?

thanx

<<Jaxx that looks good, how do like it?

Kick in the fast/gradual?>>

hi M F. i prefer kick it in gradual mode, it's more soft sound.

in fast mode become big powerfull to much quickly, but either (fast n gradual) are fantastic and different sound come from the same amp.

the scheme posted on schematic heaven is accurate.
i comparate it with schemes posted here and with datailed photos from an original komet 60. perfectly the same amp!

i have done one last week, sound incredible.


the 5k8 50W OT is the right one.

if you need the soldano atomic scheme go on

http://www.schematicheaven.com/newamps/ ... omic16.pdf

this is right.

PT may be a 275-0-275 120mA / 6.3 4A
8k pp OT it's good one.

hi M Flower, i'm very happy for your results!!! this may will be my next project. so, if i correctly understand, you use the 4k one, to have about 60W output. everywhere 5k8, 4k8 or 4k are not the problem. Vbb*Vbb/Ra_a is not the properly/accurate formule to have the exactly power output but have si...

did anyone already do it with good results?



thanks guys
