I’ve only owned two Kay tube amps, and they were both keepers. One was a pretty standard (for its era) dual 6V6 with tremolo (a really rich and deep tremolo). It had a tone pretty close to the Silvertone 1482, its Dano-made Airline counterpart, the rare 1964 Ampeg Reverberocket with 6V6’s (wow, what an amp!) Lectrolab 600B (though this is the best of the bunch, IMO) and any number of other cheapie versions/variations of a Tweed Deluxe.
I wasn’t in the market for any more amps, but how could I pass up this Lafayette LA-75? A buddy of mine (thanks Rob S.!) sent me an email, letting me know that this baby was on ebay for a really good price and that I should snatch it up. “If you love the (Valco-made) Harmony 415,” he said, knowing it was one of my favorites, “you’ll love this one. Similar output and tone, only out of one 12” instead of two.” And he was right—and then some. I do love the duel EL84 Valco/Harmony 415, but I think I like this little sleeper even more.
Last month, I was talking about the very cool little Guyatone 535 model that takes 2 EL84s (6BQ5s) for a clean, very chimey, shimmering tone. Plenty of British sounding chime and a great amp for 12 strings and clean tones. And this month, I’m going to talk about the Kalamazoo Reverb 12. Here’s another dual EL84 combo that gives further evidence that the circuit design has a lot (most everything) to do with the tone of an amp as, beyond sharing the same output tubes, it has very little in common with last month’s entry in the cheap amp chronicles. This amp has some great cleans, too, but they are nice dark, woody cleans—not the glassy chime from last month’s entry.
A few months back I talked about how great the Univox U-45 is. And I figured I’d talk about more vintage Univoxs this month—specifically the 305-B which is a really great amp with 6973 output tubes. And I will (promise) do a column about that model Univox, but I stumbled onto this rare Guyatone this month and wanted to share this rare bird with the My Rare Guitars world. So, while I am stepping away from the Univox models, I’m still stuck in Japan in the 60’s with this Guyatone GA-530A.
This month is the first part of a two-parter about Vintage Magnatone Amplifiers. This month, I’ll be focusing on one underrated and rare model, while next month I’ll break down the 5 distinct collectable (i.e. tube and mostly vibrato) periods of Magnatone Amps (from the late 40s to the late 60s before they went to Solid State models in the late 60s before going belly up in 1971).
The Hilgen “Victor” Model R2522. For the tube geeks among us, this starts with a 5AR4 rectifier before running into a couple of 12AX7s for preamp and reverb send duties. Then comes the only expensive and hard to find (although not impossible) tube—a 7199 for ‘verb recovery. From the factory, it came with a 12AU7 for phase inverter, which I switched out to a 12AY7 for a little more drive on the output tubes. I tried going up to a 12AX7, but that made for too much gain and resulted in a mushy, compromised output. The 12AY7 gives it more heat than stock, but still retains the crisp, tight, articulate character of the amp, as intended.
Among the best deals out there are the Japanese-made Univox tube amps of the mid to late 60’s. There are some rare birds out there that are worth keeping an eye open for, but the one you see most often, among the low-priced, great sounding Univox tube amps, is the U-45B Model.
What’s an affordable, well made, very cool and not ridiculously expensive amp that’s like the 1624T? I’d say you might want to look at the Univox 202R. The early version of this amp is true point-to-point (before 66 or so, it seems – there’s not a lot of information on Univox amps). Later versions are printed circuit board, like the great little Univox U45 amps (they are mini tone MONSTERS). But the circuit and cap and resistor values stayed pretty much the same. If you can, it’s always better to find the point to point ones, as they’re easier to work on and tougher built – but the PCB ones are good amps, too. Univox amps were made in Japan (all the ones I’ve seen) – most of the ones I’ve been under the hood of were made at the Guyatone factory, and then imported to the United States and branded with various names (see below for some of the other names for this amp).
One of the true major players in oddball amps, the Silvertone 1484 guitar amp is pretty well known. It’s so well know, that it may not actually qualify as an oddball amp. But it’s still from the great Nat Daniel, the man behind the awesome kings of Masonite and lipstick pickups and wallpaper-as-Tolex’ the Danelectro company, who designed and produced some of the greatest oddball amplifiers ever done.
And this month, I sing the praises of another obscure and beautiful amplifier, in this case a 1966 Lectrolab S 400. I’ve seen a few Lectrolabs over the years and they are all pretty cool amps. The 400 series seem to be (and this is based only on observation and scattered information. No one seems to know very much about these) all single-ended small amps with a single EL84 for output and one or two eight inch speakers. The 600 series are more in the 15-20 watt range with either two 6V6’s or two EL84’s (driving a twelve inch speaker), depending on the year. And the 800 series, which I’ve never seen in person, I haven’t been able to find much about, other than that they seem like later versions of the 600’s. The 900 series are El84-equiped heads (very rare).
