Electrolytic replacement in old receiver
The big can electrolytics have leaked out goo some time ago in my
Technics SA5770A. The only replacements I found while searching the web were from newarkinone (United Chemi-con U32D80LG223M63X79HPC). I need two 22,000mfd @80vdc. Their price of $14.53 each seemed way too cheap. Is there another source? Or will these be ok? The receiver still plays ok, but I know a catastrophic end is coming if these should short out. |

NewarkIn One is a great distributor -- they have been selling a lot of stuff
through ebay to reduce inventories. Jack "Dan Busetti" wrote in message om... The big can electrolytics have leaked out goo some time ago in my Technics SA5770A.

If you want, you can buy them from me at $48.77 each. (:) Big can electrolytics are generally cheap. I'll sell you same "audiophile" ones at twice that price, if you insist ;-) |

If Golds costs $977, what do Platinums cost? I ordered a pair from newarkinone for $29+ shipping. I suppose this big Technics (165 wpc)is worthy of Gold, but utilitarian units will have to do. |

So I rounded down .06. I ordered (2) $14.53 units. Speaking of the PS caps, Technics advertising says this unit has "conservatively rated power supply capacitors." |

I looked up the specs on this old classic at http://www.vintagetechnics.com/receivers.htm At 165 wpc, its a brute. +/- 80 volts and 22,000 uF is LOTS of PS filter cap for a receiver, but for a machine this powerful, its about right. There is a picture of the guts at http://www.vintagetechnics.com/receivers/sa5770.htm Looks to be nicely made. Note particularly the 4 gang (or more) tuning cap. A simple low frequency FR test will give you an idea as to whether any of the other caps in the receiver may have partially failed in a more concealed fashion. Normally cheap DVMs aren't good for FR tests at high audio frequencies, but most of them are good enough to get a represenative idea of what's happening at 400 Hz, and 20 Hz. If the response at 20 Hz is more than a dB or two down from 400 Hz, you've probably got some other dried-out caps to deal with. |

They bolted in and I used some terminal strips to anchor the leads on the screw terminals. B+ B- are 74.5 vdc. Sounds much better than before, more power, definition and detail. Will drive my Infinity Studio Monitors to concussive levels. I have a test CD from my brother I can use to check bass response. |
