Got a question for the pros:
(Handy Andy, Nomad, Shockwave, etc...)
This question regards aligning L40, L42, L43 and L44 (most galaxy styles) to eliminate harmonics, spurries, etc...
After you've adjusted all you can on the above cans to eliminate as much mess as possible but still have some spikes, is there another way to rid a signal of spurries that won't come out? Like cap swaps, resistor swaps, etc...or am I pretty much stuck with what spurries I couldn't ALIGN out?
Here are some pics before I did anything and after aligning those 4 cans as much as I could:
Before:
After:
Sorry for pics being flipped.
Are there any caps or resistors I could play with to clean it up more?
Radio is a general lee (dual mosfet version). No swing mods, looks to be original finals. Passthrough gets scorching hot within 10 seconds of keying up. I did replace both 1000uf 25v caps with new 3300uf 35v, the 330uf 16v cap next to passthrough to a new 330uf 35v. Replaced L40, 42, 43 and 44 cause someone cracked the cores.
What else can be done to the RF stage to clean up leftover spikes when no further adjustment seems to work?
Using an Agilent E4411b spectrum analyzer set for no atten. at a reference level of -10db down, sweep at 200ms
