    The outputs are 6L6GC, the letters are important and 12AX7s have nothing whatsoever to do with rectification. Just trying for accuracy.

    I must admit that I want one of these myself. I'd love to hear how it sounds through a pair of my 4Ω Acme B2 2x10 three way cabinets. That said I can't see myself playing in a bar til two or three AM for little pay. Maybe I'm just getting old! LOL

    Personally I wouldn't risk it. Damage you can see has no bearing on what is unseen!

    On the market you can find small boxes with three or four SpeakOn sockets to allow chaining of your cabinets. For someone who is handy with tools these are easy to make yourself. Make certain sure when you chain speaker cabinets that you ensure that the final impedance of the load thus produced is within the abilities of your amplifier. Edit: Something like this: https://www.ebay.com/itm/271617232407?epid=2255992147&hash=item3f3da60e17:g:sXQAAOSwT5tWMNK5 One final point is that when and if you build something using SpeaskOns always use the NL4 connectors. These are pretty much the standard on both amplifiers and speaker cabinets.

    just for accuracy; the tube is a 6L6GC. If you tried a real 6L6, which is a wartime output tube in a metal envelope, it would melt very quickly. I'm just pointing out that the letters after the type are important.

    I didn't notice that. lOL

    Shouda got one for the TV while you were at it!!

    It must be time for my nap!!

    One should be careful to keep heater draw in mind when substituting output tubes. The V4 was designed for 7027A outputs which draw 0.9A at 6.3V each. 6550 and KT88 tubes need 1.6A each. That's a significant difference. Some of the newer output tube pull as much as 2,5A for their heaters. This increase equates to a shorter life span for the power transformer.

    I'm glad you got it sorted. I have a soft spot for the AC30. The top boost AC30's were arguably one of the best sounding amps for guitar at the time. In 1968 I used a borrowed AC30B at a gig at the Silver Blades Ice Rink in Liverpool. It was a sloped stage and the VOX was wandering down the stage but it handled everything my Precision threw at it. Memories! LOL

    If the OP has a multimeter he could measure the DCR of the voice coils which will indicate what the impedance may be.

    Is there a model number for this beast? I can see if I have the schematic. That should settle the matter.

    The battery test is best performed with a 9V battery. it's easier to make contact with the terminals of the driver(s). When you have fixed the wiring applying the battery across the jack plug should make both coned move in the same direction. This checks the polarity is correct.

    It's usual for a two speaker combo to have the drivers wired in parallel for a 4Ω load. The output jacks are labeled 4Ω too,. Wired in series a break in any of the wiring will silence the unit.

    Are you sure you weren't a grudge baby? Someone had it in for your dad. 🤪

    If you decide to gig this, stack the 115 in the top position so you can hear it's cries of pain. Really a 115 is a terrible match for a 410. Otherwise enjoy!!
  17. BassmanPaul
    So what was the result?
  18. BassmanPaul
    How are your speaker cables and what connectors are they using?
  19. BassmanPaul
    I may be wrong but I thought the 410HLF was a 4Ω box.
  20. BassmanPaul
    For interest what cabinet(s) and what impedance were you using with the amp when it failed?
  21. BassmanPaul
    Which is exactly what I do with mine.
  22. BassmanPaul
    Agreed! A single 15 is a very poor match for a 4x10.
  23. BassmanPaul
    Speakers don't have resistance they have impedance. Just correcting for accuracy.

    My Mum and Dad flew over to visit. My Dad asked if we could take a day trip to see the Rockies. I was so sad to tell him that they were as far in the opposite direction as the UK is from Toronto. 😔 I would have loved to take him to see them.

    I hope it works well for you. Enjoy!!
