    As far as I know it was made by a radio repair guy in Zagreb - Croatia in the 70s or 80s. What tubes do go in there?

    I don't believe anyone will be able to answer this for you on a forum. It would likely need to see a tech and get some voltage readings and ideas about the schematic before anyone could make a guess as to what should go in there.

    Given the lineage that you describe, that's not a good question to guess at. Take it to a tech.

    It says "Fender Deluxe Reverb Amp" on it and has the same controls. Must be a copy of a Mesa Boogie Mini-Rectifier. o_O

    What are those tubes? They don't look like 6V6 to me though.

    Wow!
    Hand made OT!
    If those empty sockets are nine pin miniature I'd try 12ax7 since even in Croatia tubes is tubes and a copy of an amp is a copy of an amp. YMMV!
    It would make sense to try a 12at7 in v3 since that would likely be the reverb driver tube next to the reverb transformer, again though, if the sockets are nine pin.

    Those el34 power tubes may or may not belong there...

    Is

    It does say that, but is it 1:1 copy? Don't know much about Deluxe reverb but the number of sockets doesn't seem to correspond. I'll take the chassis out this weekend and let you guys take a look.

    Personally , I’d just start stuffing tubes in there.

    It’s gonna work eventually !

    Have fun ! You only live once ! :confused::eek::confused::eek:

    The only missing tube socket is the rectifier, which is the least essential tube, and we know for certain it has a diode rectifier since there is no rectifier tube!
    Otherwise the six preamp tubes with the reverb transformer in the middle of them is a copy of the DR.

    Probably wound by Nikola Tesla himself? Just kiddin', but his birthplace is about 30 miles from me. I'm not good with alternate current. I've built many pedals but know close to nothing about tube amps. Guess I'm more of an Edison guy .:D

    Perhaps a picture of the wiring inside would help to see if it is possible for anyone to tell what circuit was used.

    It's got a speaker with a whizzer. Those are more or less obsolete these days, aren't they?

    It's not a guitar speaker, it's for hi fi. Is it a 12" or 10"?

    Have you tried calling Ivan Klancir? Maybe the phone number on the back is still valid. May need to add a prefix for the area.

    "No such number, no such zone". A lot has changed here in the last 30 years. This amp was probably built while Marshall Tito was still alive. :lol: It's a 12" speaker. What part of Europe are you from?

    Romania. You're right, it's only 6 numbers. You just add a zone here to older 7 numbers, but 6 is pretty old.
