[R-390] caps. n trimmers WANTED (Pete Williams)

[Roger Ruszkowski]

Pete,

You may give Fair Radio in Ohio a call and ask for some RF cans for the 
RF deck. It may be easier to just swap out the can than to try and replace the 
trimmers. 

The trimmers do come apart and can be cleaned.

Fair Radio no longer list the parts in the catalog or on line.
but do have then on hand.

Sale of parts is so low against the cost of keeping up a web page 
or printing that they do not list everything.

Call and ask. Get a price and send a check with a letter
listing what you agreed to buy.

You could ask here on the reflector for the cans you would like
and see what you get offered.

Again we do no advertise here because the effort to make up list
and post stuff is just not cost effective.

Aggravation exceed return on investment.

Roger AI4NI

Pete,

One source I found is Surplus Sales of Nebraska. They have all three of the 
trimmers you're looking for as "Authentic tab trimmers as made by Tucsonix for 
Collins Ham equipment", not inexpensive though, $6.95 for 1, $6.35 in lots of 6 
and $5.95 in lots of 25. Don't know if they mix values for quantity discount. 
They can be found at: https://www.surplussales.com/Variables/Ceramic/CerCap7.html

Radio Daze (http://www.radiodaze.com/category/419.aspx) carrys them for $1.50 
each, but only has 1.5 - 7 and 3 - 12 in stock at this time.

Hope this helps.

Garry
