    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!!
  8. BassmanPaul
    So what was the result?
  9. BassmanPaul
    How are your speaker cables and what connectors are they using?
  10. BassmanPaul
    I may be wrong but I thought the 410HLF was a 4Ω box.
  11. BassmanPaul
    For interest what cabinet(s) and what impedance were you using with the amp when it failed?
  12. BassmanPaul
    Which is exactly what I do with mine.
  13. BassmanPaul
    Agreed! A single 15 is a very poor match for a 4x10.
  14. 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.
  16. BassmanPaul
    I hope it works well for you. Enjoy!!
  17. BassmanPaul
    Make sure the cabinet you use matches the output impedance of the amplifier. IIRC that's 4Ω.

    The Yorkville factory is a couple of miles East along Kingston Road from my home. they use Hammond transformers and always supply proper documentation and service manuals for their products. They are very reliable and don't sound bad at all.

    <Sigh> Nice bit of quality diagnosis there! 🙄

    Sad to say that I have a four channel 300W per sitting in my garage. If you were nearer I would have given it to you.

    When I left the UK in late 1973 I brought with me both transformers from a SC150. I designed an amp around them and gigged it for a while before I sold it and went SS. I have to admit I loved Partridge transformers!

    Then you have no choice but to stow it in the trunk! LOL

    See if connecting the Effects Loop Send and Return with a signal cable helps any. An intermittent in the switches here might give what you describe.

    Like most countries, Canada has it's problems. Here in the Greater Toronto Area we have our share of gun crime but not at a level as the US. We arrived here in late 1973 and Canada has been mostly kind to us. I ended up working for our electricity generating utility. Now retired I have a reasonable pension and an excellent health benefit plan that covers just about anything.

    Me too! Especially after they banned me! LOL
