[Hammarlund] SP-400X and 210

[Al Santangelo]

Hi guys
New to this list and always wanted to play with the older SPs.
I have a chance to obtain each of these receivers. The 400X comes with
the PS but is missing both audio transformers. Looks like average
condition, no cabinet.
The 210 looks complete no PS. Anyone replaced the paper caps in these
or other thoughts on refurbishing etc. and the variable selectivity.
Looks like they should produce some nice quality AM audio.
Thanks
