Hi, inquiring of any like minded people that have encountered this fault as I dont use linear amps but have repaired the odd 1or2 thought i would ask for opinions very high vswr at mid range power or all and any the linear is virtually identical to the rm range except this b300p is using 2 2sc2290 instead off mrf455 worked perfect for 2years plus any ideas the Ariel in use has a ratio of 1.1 on all major bands ihaven?t tested to a dummy load as of yet as its not my linear a(coupling stage maybe).Any ideas.

Repaired this amp ages ago well abused earth lugs on the preamp board- Pwr select-dryjointed-xtreamly bad solder all over. long gone-now. surprised this post is still active.
