I had a pair of these. I remember them as great powered speakers. Designed as near field monitors they had enough capability, in power and driver range, to use as regular hi-fi speakers in a 2-channel setup in a small room. I sold them to a friend who loved them and I particularly remember being at his house and enjoying hours of listening to old Savoy Brown and ZZ top tracks. I don't think Foster has anything comparable to these today. The quality of the sound makes these well worth the repair I'd have to surmise.
So mine have blown tweeters I have a pair I checked the board and they look immaculate and then plugged in a tweeter and it worked but the power isn’t matched well way too much bass to tweeter but definitely works what tweeter should I buy? I can’t afford $100 for originals of I can find them
Hmmm, you should have followed your own advice and looked up the data sheets, if you had you would have seen that the SAMXON GS caps that you decided were bad have infact got a + or - 20% tolerance when brand new so even at 5800uF they would have been in spec. ESR in caps goes very high when they are faulty (many ohms) and VLOSS is apparently leakage current but has been proven to be totally inaccurate on these meters ... so there's not really any info from those meter readings to confirm those caps are bad. Those meters do have a use for quickly giving confirmation if transistors are open/shorted and diode testing but not accurate at all for capacitors unless very bad (e.g. many ohms ESR).
