I had to make a couple of concessions when I ordered the resistors
for the Bugle.
The main issue is Digikey has order points of 5 and 200 for the 1k and 13k
resistor. I did not want to buy 200 each of these.
So, I went to Mouser instead. I found all of the resistors I needed in the
Vishay/Dale line. The specs. are the same, 1/4WATT 1%, except they state "Rated to 1/2WATT." Also, the 1.43K resistor was only available in the Vishay/Dale military line. The specs. are the same. except in this case no "Rated to 1/2W" is not stated. Any issues with this?
I also bought all of the same resistors from Mouser in the Xicon line
(10ea minimum). However, the closet I could find to 1K was 1.02K. I am
guessing that this is O.K.
Also, the 8.45k Xicon is backordered. Can I substitute the Vishay 8.45K in
the circuit with Xicon stuff?
I am substituting 604ohms for 1.3kohms in R3, R5, R21, AND R23. According
to the on-line calculator this will yeild between 52db and 53db. My target
was 50db.
