Robert, it doesn’t need a 3 prong cord! As a matter of fact, 2 prong amps are less problematic with AC hum as you can reverse the plug (polarity) to remove hum issues. The amp is safe as it is. I’m a full time musician and have used two prong vintage amps for years and never gotten shocked. Look up what Skip Simmons says about this very subject.

Here is some advice on “wanting to be fair”. About 25 years ago, an old man past away and his family was selling off his property. He had no living children, his nephew was entrusted by the others to do the selling. I bought his Gibson Granada Banjo {NOT a pre-war} he was offering locally. Right before I was leaving, he mentioned a guitar he was selling as well. I asked to see it. He went and brought back an all original 1939 Martin D-28. I couldn’t believe it. When I ask him what he wanted for it, he told me new one’s were bringing $1500, so a used one as clean as this one was should bring at least $1,000.00. Remember, this was before TV shows like: “Antique Roadshow” and “American Pickers”. The internet was just taking off in the mid 1990s, so there wasn’t the wealth of information out there like there is today. Instead of immediately going to the bank and getting the grand, I tried to be honest. I told him what he had, and what I’d pay for it {competitive to what a vintage dealer would have offered}. He was stunned. Now everything had changed. He said he would have to contact the other family members and “get back with me”. After several days of not hearing from him, I tried calling him, a couple of times. No answer. About a week later, I saw the guitar: On the cover of Elderly Music’s vintage catalog. So much for being honest. Never again. I learned a lesson that day. It’s not my business to educate people on the value of their goods. If they don’t know, their ignorance is my gain. The guy didn’t even offer to buy me lunch at Wendy’s for what I had done for him. Not even a “thank you call”, NOTHING. I’m not advocating for cheating people, just know that being the “good guy” often times doesn’t pay. People always want more, even if it is just a little. Make her price her goods, then pay what she says.

I’m about to buy a 1961 Vibrolux. All original except a Radio Shack speaker. Cosmetically very-good. Will need 3 prong cord, caps and likely tubes, servicing. For sale from a private party. What might be a fair price? Original owner passed in 2013 and his widow now wishes to sell. She doesn’t know how much to ask, and I want to be fair. TYIA.

I own a 1962 Vibrolux “Brownie” amp that was a Christmas gift to me from my dad, Christmas 1967. My first Amp. It is all original except that I removed and stored the original Oxford speaker and recently replaced it with a 2007 Jensen P12N. It also needed to be recapped to bring it back since the E-Caps were dying off, and a grounded power cable, so there’s that. The thing absolutely sings! It, is my #1 amp If I don’t use my 1964 original BF Deluxe Reverb, or 1966 BF Super Reverb, or one of my two 1960’s Tweed 5E3 Deluxe’s or my Tweed 1962 Champ or my 1968 SF Drip Edge Champ. All my amps are original and I am blessed to possess and perform with some of the greatest amps from one of the greatest amp & guitar designer/builders that ever lived; Leo Fender. I have many other makes and brands to compare with, all of which have great and differing useful sounds and tones. Forever Thank you for my Fenders, Uncle Leo!

If you look at the original schematics, you will see that the brown Vibrolux only had a listed plate voltage of 365! That’s extremely low for a 6L6GC amp. That’s like the voltage in a tweed Deluxe. By comparison most Deluxe Reverbs have a plate voltage of 415-425. That’s why the DR sounded louder. I had one of the brown Vibrolux’s and it sounded anemic to me probably because of the mentioned low plate voltage. 6L6GC’s need to be up in the 435-450 volt range to sound good.
