[Elecraft] KPA3 vs KPA3A

[Mark E. Musick]

Yes, Eric you can. 
This is something I was considering myself and investigated.
Wayne said the KPA3 and all other K3 options could be used in a K3S.
Wayne pointed out that the basic design and specifications of the KPA3A are
no different than the KPA3.
The KPA3A does have more pins than the KPA3 connecting it to the K3S RF
board. Wayne said they did this to minimize voltage drop.
So it appears you can put a KPA3 in a K3S, but you can't put a KPA3A in a
K3.
As I was considering buying a K3S/10 and moving the KPA3 and other options
from my K3 to a K3S/10 I saw a post from Don W3FPR advising another poster
against this as the KPA3A has current production RF transistors and other
components. Meaning how long will the current components in the KPA3 be
available.
Taking Don's advice I decided to purchase a K3S/100. It arrived Thursday and
I will be moving the sub-receiver, filters and other options from the K3.
Another thing to consider, if you are going to sell the K3, as I am, a
K3/100 will probably be an easier sell than a K3/10.
I did purchase the KAT3A tuner because I feel selling the K3/100 with the
KAT3 will also make it an easier sell.
One other point, the KXV3B is not an option with the K3S as the KXV3A was
with the K3. It is standard equipment and comes with the purchase of a basic
K3S/10 or K3S/100. If you have the KXV3 or KXV3A in your K3 you can let that
go with the sale of the K3.
Also, if you have the sub-receiver in the K3 and are moving it to the K3S,
you will have to purchase a K3SYNA board for the sub-receiver.

Guys,

 

Is it possible to pull the KPA3 and KAT3 from my K3 and use them in a K3S?
