[Amps] best deal for Mallory caps?

[Charles Harpole]

I purchased the needed caps in Bangkok's electronics wonderland...5 sq blocks of shops... at about $1 usd each and they fit easily under the existing board with lots of room under where the long original ones were.  Fit in the same holes with added spade lugs..... Easy fix with no outboarding needed.  73, Charly
