This tells me 100-200w are being sent back to the PS by a partially
resonant choke, thus the "brown spots".
You need to use an accurate grid dip meter with the choke in circuit to
measure for any resonances near the
freqs you plan on using. If you make any changes like adding or removing
windings, you would need to check
all the bands again! If the choke opens and unwinds during operation, it
could short the B+ to ground! Bang!

I use my tl922 on the WARC bands as follows: 30m - bandswitch on 20 17m - bs on 15 12m - bs on 10 Power output is 1 - 1.1 kW compared to 1.2 - 1.3 kW on non-WARC bands.
