Thank you for your video. I just bought a 1960 B cab yesterday and someone replaced the original speakers for vintage 30's. When i test with the multimeter i get like .3 ohms on all settings 4, 8 16ohms. The cab is wired correctly from what i can see. Ive watch a few video's on wiring. So it has to be the jack right. I know you say you replace them anyway. Just seeing what you think.
@@mikesmith3662 have you tested each speaker separately? Vintage 30s are rated for 16 or 8 ohms, best way to check is just grab a solo 1/4 jack get the speakers soldered to it and test that current. If you are getting the same reading on all channels that sounds like a jack problem. You should get different variables even if it’s not wired correctly.
So today I bought a proper multimeter to test the ohms. The other was not what I needed. On stereo I get 7 ohms out of each side but when I try mono. It get 7 ohms out the 4 ohms side and I get 13 ohms out the 16 ohms side. Are the original speakers 8 ohms speakers? Cause these v30's that were put in are 16 ohms. With switching the speakers with different ohms, will it cause the 4 ohms option to run at 8 ohms instead or does the input jack assembly need to be replaced to function properly. I would like a 4 ohms option but I don't think it can do that now. Just seeing your thoughts. That you for your time.
@@mikesmith3662 those speakers are rated at 16ohms if your getting those readings. There is something going wrong with the 4ohm jack if your reading 7ohms it should be somewhere around 3.1-3.7 ohms and since ite readings more than twice that then the sort is open. It’s not the end of the world you can get away with it but you would be risking your Power transformer on your amp or the speakers themself. A replacement jack plate is like $50 and you would have an easy of mind and know the cab will last you another 20-30 years easy: those early pcb boards that control the wiring signal path to switch between ohms are finicky. I recommend getting them from amplified parks if your in the states, they are out of stock last I checked but they are good are restocking every few weeks. Otherwise stick to the correct readings the 8ohms for stereo or the 16ohms for mono
@@MistaMahcos cool. I think it's the input jack assembly too. I'm gonna buy a new one. I found one in japan on ebay. I would like to run at 4 ohms. I appreciate your time and input. Thank you. I'm in Arizona aswell. I live in Cottonwood. 🤘
Thats some high quality content! Thank you very much. I didnt know that you are a AC/DC fan. RHCP and ACDC are my two favourite bands.
I bought an SG as my first guitar only because of angus 🤘
This was my first guitar aswell🤟. The Young brothers are my biggest guitar Heroes along with John.
