Hi David I do not see any problem, at least for R6, 7 and 8. You have an M 10 db attenuator and mesuring R6 or R8 you have 100 ohmswith 168 ohms in parallel. So the result should be 62.68 ohms on you DMM! R7 is 68 ohms with 200 ohms in parallel so you should have 50.74 ohms! So as the series of

Thanks to David, Don and Gary for making me feel better this morning about my resistors. I have been testing each prior to installation but when came to that group, got lazy and decided to only check them AFTER installation...which then made me wish I hadn't gotten lazy!!! Great object

Working on my K2 (page 48) Assembly, Part II and as I'm installing the wad of 1/4 watt resistors, I have been measuring them after installation. R6 and R8 are both listed as 100 ohm resistors (BRN-BLK-BRN), but after installation, both show 61.6 ohms on three different DMM's..while R7

David, I am not sure how best to put this... Imagine you put a resistor of infinite value in parallel with your 100 ohm resistor and measured it at the ends of the 100 ohm resistor; of course, you would see the 100 ohms; what if the two resistors were 100 ohms each? well, being in parallel,

Just started on my K2, SN#6048...and am new at this process. I seem to have smoked the resistor r20 in the control board, as I installed it...a 2.7 ohm (Red-Violet-Gold) resistor which now reads .001 on the DMM(I think too much heat for too long as I attempted to reposition it after it

David, Most all the resistors in the K2 (including R20) are 1/4 watt. The only 1/2 watt resistors on the RF Board are R50 and R58. To the best of my knowledge, all resistors shown in the schematic that are NOT 1/4 watt are designated with the power rating. In most cases, a 1/2 watt can be
