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,
