I’ve noticed that my 1950’s Rickenbacker Bakelite tends to suffer from typical single-coil hum. This is especially noticeable at band volumes. Does anyone have any experience with shielding the co ...

Hey Steven, I had good luck with the all-passive mid control from the 70's Peavey Session and LTD amps. Just scale the impedances up for tubes and it works great for a variable mid cut.

Hard vacuuming processes which was what made tubes last long and sound good has been hidden from those who make them today and the equipment for this process is not easy to come by to copy.

I'm cu ...

Pull each tube starting with the one closest to in the signal chain to the input jack and moving down the signal path towards the output tubes. See if/when the hum goes away. This may help you find w ...

I like Relaxin' and Stylin', then No Peddlers and Son of No Peddlers. They're all great though.

The shop where I work has had a bunch of vintage Echoplexes in lately so I've been getting really familiar with what they sound like. The Belle Epoch sounds pretty much in the ballpark to me. It's n ...

Bump for updates.

Nice! Thanks as always.

I had a question about the weight of this amp. It weighs 50 lb 8 oz with the cover on. Also thanks Dennis! It's a great-sounding amp.

I'm selling my Milkman Sideman 50 Amplifier to move to a head-and-cab setup. This amp has been back to Tim Marcus for a complete update to the latest version of the 2-channel sideman circuit. It has ...

That's a mighty tricky reverse slant in bar 2!

Cool! I was just listening to this today at work and thinking what a cool performance it is. Nice work with the transcription!

I have a quad of JJ 6L6GC's in my Blackface Showman and it sounds great. To me the JJ's have a nice glass-y, spacious, scooped sound that works for steel and they're pretty cheap.

Thanks Guy, I've always really appreciated your transcriptions!

Another recent JB-related discovery for me: Spotify and Apple Music have three Hawaiian-themed albums by Paul Page and the Rainbow Trio that feature Jerry Byrd.

With something as cool and valuable as a Tweed Bassman I would definitely recommend having a pro do it. If it was something modern, less rare, or a personal project I'd say go for it but there's quite ...

The 12AU7 specs 10.5 mA with and -8.5v on the grid. With less voltage on the grid you'll see an even higher current draw. The 12AT7 has a spec plate current of 10 mA with -12.5v on the grid so the c ...

Thanks Andy for turning me on to Ed Bickert, I spent all morning listening to the Paul Desmond Quartet. What a great player!

I'd go with a JJ Electronics 5751 and find a retailer that tests their tubes and offers at least a 6 moth warrantee. That would be Ruby (Magic Parts), Eurotubes, and Antique Electronics (Tubes and Mo ...

So we have no data of any kind to confirm the hard/soft vacuum issue. We don't know if this was something that was actually consistent between samples of vintage tubes or if modern manufacturers are ...

Hi Godfrey and thanks for the detailed answer. Do you have a link for some evidence that new production tubes have less of a vacuum than older production tubes or that different brands of old producti ...
