Howdy dear friend seller, I just got the order in perfect condition, many thanks, keep asking more RF amplifiers, by its stall that still recommend of all ways to this excellent seller, and this excellent and prestigious shop.Best regards from Talagante, Chile;Eduardo Fritz Collante

Inside is no problem. I get them. Thank you very much.

very well packedwill build one during the x-mas holidays

1 star less for not mentioning or labelling the SMD capacitor values. I don't have an LC meter to measure the values and SMD capacitors do not have value mentioned.

All is working as described, little bit is difficult to make it without full manual. But seller gives links who makes them. Main transistor is not new, so it can be bad. But i my case it was good.
