[R-390] R390A

[fev]

Hello, I bought here in Argentina a R390A manufactured by Collins.
It works good, maybe not  so good like I suppose it must work , but my
question now is how smooth must be the tuning , in my case is a little
hard and
I get a little tired tuning it if I compare it with other like the TS830
or the old SX100  I have. It is posible working on it to obtain a nice
tuning or it is like it is? 
The second problem I see or feel is that it had some play in the
mechanismus to tune, is posible to adjust that or this is not posible?
Maybe my question are stupid but if one of you say me that is possible
to make the tuning better my sicological energie will be stronger to
start with the 
restoration of this receiver.
Thanks in advance for your comments and sorry for my not good english.
