'73 Fender Deluxe Reverb | Did It Forget the Words?

[@michaelhager4270]

I have that amps sister. 1973 Deluxe Reverb, even says Costello inside. It's a lovely little beastie

My first thought once you had checked off all the obvious was dirty supply. Especially if they just had a proven surge at the source. Could have just been a load kicking around somewhere. May have even been cleared when he powered up again. It was never mentioned if it was tried at another power source or if he just thought it best to have checked before causing more damage.

Just a general observation .. I always push wires away from threaded screws, just in case vibration might cause a chaffing issue. Rare .. but happens. I noticed a few wires I would have rerouted slightly. I’ve got a ‘68 Bassman on the bench that I’m anxious to get back to. My wife and I are in Paris for the month .. she keeps reminding me of romance and to forget those silly AMPLIFIERS back home 🤪. -BigHammer Labs

Paris is a wonderful city; I envy you, and my wife envies your wife!

Thanks for the GREAT content on this channel!! Unfortunately, having seen so many of your vids, I'm now afraid to send my amp to anyone local....

Gremlins in the church...call the exorcist 😮😝🤣😎👍

What a nice amp

[@roncarter2188]

What brand screen resistors did you use?

[@moorec1053]

A little bit of magnet humor there....... 5:20 🙂

Hey man! Do you know if there were any circuit or material changes from 70 to 79 with these silverface Deluxes? Thanx!

[@pparise1]

Any idea about the “Richard Smith” engraved in the amp? I had a ‘74 Deluxe Reverb that had the same on it. Really great sounding amp that I wish I still had.

[@BradsGuitarGarage]

Just curious what you guys mean when you refer to a "power surge". To me, that would mean a sustained overvoltage event for a second or more of some sort. "Spikes" is the term I'd use when referring to an inductive spike from a motor or something on the mains line turning off. "cut" or something is what I'd refer to when talking about the power dropping out for a moment.

[@PsionicAudio]

Sometimes the voltage here shoots up over 130VAC. This can last many minutes. I have a power conditioner that all my main shop stuff is plugged into and it shuts everything off until the power comes back below 127VAC. But with that protection, amps (and a lot of other electronics) don’t like 135VAC mains very much.

[@kevinfarrellUK]

Just wondering, would you recommend using a surge protection breaker?

[@Tonetwisters]

That means it likes to hum.

[@justinpaquette224]

Is there an amount of mV that is ok to be on the eyelet board? My 73 deluxe has about 200mV to 1V and my amp tech thinks it might be what's showing up on his scope? But not 100% sure. Trying to decide if I should change the board, he already tried the heat trick

[@shawnmazzeimusic9549]

Too much man

[@PsionicAudio]

Way too much voltage but no need to change the board. See my ‘79 Vibro Champ video for conductive waxed boards.

[@justinpaquette224]

@@PsionicAudio Thanks, I will check it out

[@russellhltn1396]

Strange. I can't think of a way a tube amp could get into a strange "mode" like digital circuits tend to. My best guess is the power itself - too high, too low, or noisy. Perhaps the guitar was picking up some fault currents. Perhaps a buzz from the lighting rig?

[@douro20]

5751...I guess a 12AX7 has too much gain? That's an interesting looking 5U4.

[@goodun2974]

Looks like a 5AR4/GZ34 to me. The scalloped edges are a giveaway; and 5U4's, even the 5U4GB, are larger than a 6V6. Only problem being that a 5AR4 would cause a significant over-voltage for the 6V6's ......

[@sgt.grinch3299]

I can’t remember yesterday. Don’t feel bad about last September. I know where you put your pointer.

[@BrandonPitt]

Straight into the amp for a church gig? What the hell kind of church is this?

[@danielsaturnino5715]

Hmmmmmmm :)
