[HBR] coil forms

[Dan Merz]

Hi,  I think the Ocean State forms are high quality,  based on my
impression that they are the ones made by Jim Fred.  I bought quite a
few of the SW-3 coil forms directly from him,  more or less the same
price,  depending on how many you buy.  The description in OS catalog
makes me think they are the same quality.  His are overkill,  because
they are canvas reinforced phenolic thoughout with staked-in pins.  I
resorted to his because for the SW-3,  they have the small recessed
channel at the bottom for the tickler coil and it's difficult to find
the unusual 6 pin type that the SW-3 uses,  non-uniform pin spacing.
