I warmed up my system tonight to listen. Sat down and was ready to listen to the Beatles White Album and....DAMN IT!!! the left channel was only producing the SDA signal!

I shut down the system, unplugged the amp and opened it up to find.......

The bridge rectifier in the CR1 spot had been "fried". As I said..... DAMN IT!!!

Now I need to replace the rectifier in both sides since I can't seem to find the part number that was used originally in the amp.

Sorry, just had to vent since I don't like not being able to listen to my system when I have the chance........

    Sorry to hear that Greg. Call Vlad. He gave me the value of a zener diode for a BAT mono block tube amp I have here for repair.

    Thanks guys for the sympathy. Rich, did you start your own repair shop? Or, are you just doing someone a favor? I have e-mailed Victor/Vlad and if I don't hear back from them early tomorrow I will call them. Thanks for the advice.

    Also, do you guys suggest replacing the "stock" output oil filled caps with some even higher quality film caps such as Mundorf, etc??

    Just helping a friend out. It is very hard to fix something without a schematic though. Only thing I got are three identical working circuits to compare readings to. Despite that, it still takes some desoldering to get exact readings on some parts. It may still end up going there as some traces are lifting making repair attempts too scary for me. Gotta talk to or email Vlad directly though. IME Victor is not so free with info. Vlad will still say best send it in.

    In a signal capacity, tough call as BAT used good parts to begin with. IMO replacing a real good cap wih a better one doesn't get as much mileage as replacing a cheapy. You may also affect future resale with most folks as you have strayed from BAT design/parts. Won't matter if it sounds better, it just won't be right to them. I know of one manufacturer that has a large stock of discontinued Sprague OEM caps just to keep that factory repair looking OEM.

    I had to go to ebay to get a lot of identical zener replacement diodes for this current project. Had to go to ebay to get a lot of discontinued Fairchild J309 jfets for my Krell pre. Needed quantity to find a near exact match for replacement, and it matches the rest.

    I would not as they use good parts, and you don't have as much to gain as you have to screw-up IMO.

    Greg,the part# (current /voltage rating) for the bridge rec should be printed on the side of it.For example if it's a big 35 amp 400 volt part it would have something like GBPC3504 on the side of it.

    Thanks Fred! So, if the part number is:
    GI
    DF04
    616M

    What would that mean for the amperage and voltage?

    Most amps use a GBPC or KBPC 3504 or 3506. The first 2 digits in the part number indicate the amperage and second 2 digits voltage (i.e., 04=400V, 06=600V, 08=800V, 10=1,000V).

    Correct Joe. It's a 4 pin chip. I have seen a 1A 400V version, and a 1.5A 400V version, but don't know which one it is.....

    Can't seem to find the identical part....

    And, I don't know the size for sure......

    Can't remember Rich. I don't think I searched for DF04 only. I think I had the 616M included.

    I have found 3 DF04's at mouser, two that are 1.4A 400V and one 1.0A 400V.

    Still not the right part number though Rich. I did figure out that the M in the part number means it's a "through-hole" rectifier though.

    Can't figure out what the 616 means as far as amperage goes.

    The "04" in the DF04 means it's a 400 volt rectifier. Anyone have a clue on the amperage though?

    The 616M could be mfr codes. Like Steve's this data sheet shows 1 amp.

    Rich, that rectifier is a 200 volt rectifier though. The "M" in the 616M means it's a "through-hole type" so I am assuming the 616 must have something to do with the amperage, but don't know what or how to "decifer" it. I have found some 1A and some 1.5A versions of the DF04 rectifier, but am not sure which is correct as far a amperage goes.

    They all seem to have virtually ideintical dimentions though as far as pin width and box size.

    It's late but it looks like the DF04 is 400v to me...;) 280 is RMS reverse voltage.

    Sorry Rich, I didn't state what I meant very clearly. The pdf file you linked was for a 200 Volt rectifier, but after looking at the data sheet it's actually for all voltages.

    All the DF04's seem to have very similar specs, but I just don't know how to determine the amperage to match the GI rectifier that was on the BAT VK-200 originally.
