Hi group,
Here, are the identification of the Heath Parts that are used in the
SB-200 10M modifiction that I have sent to those whom requested the
modification by sending me a SASE. This info was provided by Ed WA8ZVO
['formally one of the Hams at Heath'], with many thanks from me - and I
know also from those who hold the mod.
--------------------
Capacitors: 20-40 470pF All are 500V 5% Silver Mica
> 20-42 510pF
> 20-76 68pF
> 20-108 200pF
> 20-110 75pF
> 20-112 310pF
> 20-131 360pF
>
>Coils: 40-591 43.uH All are variables
> 40-592 2.35uH
> 40-593 .96uH
> 40-727 .33uH variable
> 40-728 .235uH
That should help you find suitable subs. Values are nominal (mid-range)
for the coils.

Enjoy!
