I have 4 Panasonic-ECG 150 uf 500 volt snap in capacitors that I was planning to use to recap a HP-23. These are new, Digi-Key part number P7452-ND. My plans have changed and if anyone can use them I will ship them for $12.00. These are not exact replacements but the values will work. They are not the original twist-lok type caps. Bob W6VY
