    The Superior Tweed Super Amplifier

    I just finished final mods to my (now) Tweed Super. It now sounds WONDERFUL, rich and chimey, worlds of headroom, and really loud when required. I write my mods which I recommend. Circuit is MOJO 5E5A Pro, stock save for the blackface Bassman OT (cheaper with a bit more 'umph'). Tubes 12AY7...

    going from tweed pro to tweed super

    I am upgrading, or maybe side grading, my 5E5A Pro to a 5E4 Super, in other words, going from a single 15" speaker (taken from a Roland bass amp) to a pair of 10" Jensens, one P10R alnico, the other MOD ceramic. I'd like to say I want the better mids, quicker, punchier response. In truth, it's...

    G&L telecaster pickups?

    I am thinking of upgrading my pickups. I hear lots of talk about all sorts, but little or nothing about G&L Alnico pickups. Designed by Leo, made in his shop, sounds like they would be excellent. Has anyone used them? I like to hear your opinions before deciding on them.

    Alex's new Champ Amp

    This is my take on 5F1, this one is built from scratch using parts scavenged from junk amplifiers from recycle shops, chassis hand formed, the cabinet from scrap wood from carpentry jobs. It is basically a 1958 Fender Champ 5F1 circuit, beefed up with big OT transformer, bigger speaker, bigger...

    Increasing headroom and bass in Tweed Champ 5F1: success!

    I have been restoring my 5F1 following years of screwing around with it as a test bench (making it push-pull with interstage tranny, dual tube single-ended, etc.). I was never happy with the bass, never could get a good jangle, never could get headroom. I saw an Uncle Doug Youtube in which he...

    weird vibrato in 5F1

    I just returned my 5F1 Champ to straight stock, just like the 1958 schematic. It seems a bit weak in output, but that may be subjective. The weird thing is when dimed there is a slow but strong vibrato, a rising and falling in volume, about 4 times per second. Different tubes have no effect...

    Fixed bias for single-ended amp question

    This is a theoretical question, although I just might try it.... Are there any fixed bias single-eded amps out there? I am looking at putting a 5F11 PT into my 5F1. It is a bolt-in upgrade to get a bit more punch into the 5881 tube I am using. It has a tap for fixed bias. The advantage...

    loss of heater circuit

    My homebrew tweed champ quit on me today. Checking the voltages I find that one tube element heater leads coming from the PT is evidently dead; the other is putting out 6 volts AC. Everything else checks out. Is heater leads failure in Fender amps a thing? I've never heard speak of it. Can...

    Putting capacitor in NFB?

    I am trying to get some of the shrillness out of my 5F1 Champ, as well as the high pitch whine and buzz. Would putting a small cap, say, 150pF across the NFB resistor do the trick? Anybody ever done that?

    How many of us are finger pickers?

    I used a pick for twenty-plus years, but for thirty years or more just use my fingers. There are several reasons: 1. never could keep picks in my pockets when I needed one. 2. works well for Ry Cooder and Mark Knofler, and several old players like Furry Lewis told me so, too. 3. I can play...

    1950 Esquire partscaster

    Fifty years ago a schoolmate sold me a 1949-50 Esquire for $10. I sold it to a mutual friend for $30. We have all been kicking ourselves over it for half a century. So I built my friend a copy of it for the cost in parts. While aqua blue (his request) and with a MIJ Strat neck (hey, I'm...

    My blackguard got a new baby sister...

    I work as a carpenter in rural Japan, and the other day on the job I came upon a hunk of 150 year-old Japanese heart pine, a 2 x 14 just long enough to make a guitar body. I started to order parts from Stew-Mac, but decided to wing it. I found a 'crafted in China Squier Jagmaster neck in a...

    10 year-old's first build

    My sons all play music, but the youngest, 10 year old Natsume, just can't keep his hands off my 1980 Tokai breezysound Blackguard. There are plenty of guitars around the house, but he has to play the one I would rather him not fool with too much. I could buy him a cheap used t-type (readily...

    ELK AMP? Anyone ever heard of them?

    I was in a pawn shop the other day and saw an Elk Amp made by the Miyuki Corporation back in the 1960's. It looked like a copy of a Fender Super Reverb, right down to the tolex and grille cloth. It had four 10" alnico speakers, four 12AX7's and some other odd tube, and a pair of EL34's. The...

    Octal Power tube wiring question

    I thought I asked this last week, but maybe I failed to hit the 'create thread' button, so I ask again. I am building a Fender-ish push-pull amp using 6V6. I see that some amps (musicmaster bass, 5F1, 5F2-A) have the signal entering pin 5, and pin 6 is unused. Others (5E3, 5E5A) have the...

    Question on wiring octal power tubes

    Looking over lots of old fender schematics, I see that some (like Princeton brownface and Musicmaster bass) have the signal entering on pin 5, while others (like 5E3 and 5E5A) have the signal coming into pin 6 jumpered to pin 5 with a 1500K resistor. Obviously both approaches work and sound...

    The Musicmaster/Harvard/Deluxe/Champ amp

    I am building an absolute mongrel. I need a really small, lightweight but gig worthy amp that I can carry comfortably by hand on trains and buses, so I am building push-pull 6V6 amp with 10" speaker in a 5F1 Champ chassis and cabinet. Impossible, you say? Read on. It is a Musicmaster in that...

    nice source for RCA 6V6 black plates

    I just got two RCA 6V6 black plates for $9.99 each from ebay. If you search for RCA Black black plates they cost a fortune. But if you look for FoMoCo (FOrd MOtor COmpany) radio tubes, they can be be had cheap. Evidently old car buffs are not into jacking up the prices for guitarists yet...

    headphones/recording out jack for tube amp

    My neighbor recently complained about the noise, for which I am guilty as can be. He even complained when I used a champ on 5 on the far side of our big old house. He may be a jerk, but in Japan that means shutdown - must not disturb the harmony of the neighborhood. So I needed to put a...

    Dropping B+ - advice wanted

    I have B+ out the wazoo, 407 volts, where about 300 volts would be better for the Harvard build. I also have a stack of various 5 watt ceramic sand block resistors, most between 200 and 500 ohms. Is there any reason why I should not put a big resistor between the rectifier and node 1? And if...

    Simple power tube shoot out

    I recently acquired a matched pair of 'holy grail' old RCA blackplate 6L6GCs. With breathless anticipation, I swapped out the 7581-A tubes, adjusted the bias, and cranked her up. An hour later the 7581-A's went back in. Clearer, quieter, louder, tighter, stronger bass, way more headroom, way...

    restlessly evolving amp saga: introducing the ProHarvard

    My first amp build was a 5F2-A Princeton. It was fun, but produced a rather worthless amp = a glorified Champ useful only for practice at home. So I built a 5E5-A Pro for gigging, leaving me with the Princeton as a work bench for modding. I added, well, everything: 5E3 circuit, OT, tubes, and...

    Best copies of RCA black plate 6L6GC?

    I am fixing to buy new tubes, upgrade from sovtek 5881's. With money to burn I would like a matched set of 1950's RCA black plate 6L6GC.....dream on.... Who makes a good copy? They need not look like RCA black plates, just sound that way, all creamy smooth and sweet. I do not need volume...

    anyone here ever add reverb to a tweed amp?

    I am torn between using my Paul Rivera Fender Concert and my homemade 5E5-A Tweed Pro. I really like the Pro, but the Concert has wonderful reverb. Yeah, I know: use the Pro and get a pedal. But I just aint that kind of guy. And I have a lot of parts lying around and just love build...

    How to build a big 6L6 champ

    I built a Princeton 5F2-A last year, and recently a Champ 5E1 (essentially the same thing). I have rebuilt and experimented again and again, trying to get a little more out of these small single-ended amps. I have read dozens of posts about people wanting to build a 6L6 single-ended amp, and...
