[TenTec] ALC issue on Corsair II

[IV3YNB op. Matteo]

Hi everybody !

I fixed RX stage of my Corsair II, it was a couple of burned diodes and a broken stripline beyond MODE knob to fix. Now the 561 is really a good receiver, I enjoy the bands with it better than thru other modern rigs.

Anyway I still have a trouble, this time on TX: while in LOCK mode and ALC knob fully clockwise, ALC steady blinks with DRIVE set from 0 ti MAX, it lits also if ALC knob is set fully counterclockwise. Keying the Corsair II, I can hear the PTT relay and sidetone (QSK works great) but output and SWR are null !!! ALC always blinks.

I don't expect you to solve my trouble, anyway I am asking someone to suggest me which board to look at first.

Also: is there any SERVICE MANUAL about the Corsair II, or I must only rely on the schematics in the user manual?

Thank you for reading, hope to receive some clues
