NOTE:
In order to avoid (or minimize) confusion in the external appearance between 50 and 80 watt models the following external components will differ.

A. The 80 watt heatsink will be bead blasted and clear anodized (same as DELTAFORCE/OMEGAFORCE) The 50 watt sink will continue to be black.
Heatsink Information that will be on the Final Production Radio

B. The DC power cord has a large black plastic inline fuseholder (15A) The 2 parts are threaded and screw together. The part looks very much like an enlarged black BUSS inline fuseholder (HKP).

C. There will be an addendum sheet to owners manual packed inside bubble wrap bag that explains the new RF lineup and gives information on a couple of pertinant VR's for setting up mic gain circuit and how to achieve max audio without destroying the audio quality.

D. The dress box will have all new pertinant information and new model numbers.

E. The S-380 will have this screened on front panel and S6 and 9 will have the 80 designators screened on SRF meter.
