I would like your expert recommendation for a tube type guitar amplifier
that I could build myself. I have built a number of HI-FI tube and solid
state amplifiers long time ago. I have also collected a number of circuits
for guitar amplifiers but not being able to play a guitar and also being
somewhat stunned when it comes to music does not help in decision process.
Requirements - 25 W, volume, tone, tremolo, fuzz, reverb. I do not need any
hand holing in how to build it so rest assured that I will not come back and
haunt you with inane questions. I am just looking for a recommendation from
a trusted source. This is a present for my daughter who has picked up a
guitar about two years ago and has not put it down since. She is very
determined to makes something of herself and I would like to reward that.
Thank you for any pointers.

after a full overhaul.

True. What really burns my but is that number of yeas ago I bought a
Fender twin reverb on a garage sale for 25 bucks. It sat in my basement for
7 years. Year after I sold it she get passionate about guitar.

The schematic that you supplied will be on my short list. I am considering a
PCB layout. Where can I get the transformers, reverb coils and the LDR
modulator? Does anybody make octal PCB sockets?

you state: "Requirements - 25 W, volume, tone, tremolo, fuzz, reverb"

actually, you should, when specifying the needs, use term like

maximum SPL you 'need' , frequency range (is it an acoustic guitar w.
pickup?),
maximum size & weight, price range, construction considerations(easy or
complicated),
etc., etc. *Then* it is easier to 'get the picture' :-), to get ya
'tailor made solutions'.

The SPL is a function of the speaker and enclosure efficiency. All I want
is a schematic and BOM. This is for electric lead guitar. I should have
specified that. The gray area is in the performance aspects of the potential
beast. Since I could not play a note to save my life I have no idea how to
specify certain attributes such as "Breaks up really nicely" or a "terrific
sustain" I assume that the break up is desirable distortion and sustain is
some kind of interactive positive feedback loop between the player, guitar,
amplifier and speaker. I guess the SPL play the role here as well.
I am not really asking for a tailor made solution because the kid is growing
fast.

for practice,
25W into a typical guitar cabinet is wayyy to loud !!

If you are in Montreal I can supply you with some parts... I have trannies and
tubes and reverb springs and all the parts for an amp of that type... if your
Email addy is correct I'll Email you... I collected a lot of parts to build a
few amps of that type (50 watt guitar) but only built one so far... I'm
specializing in 3 watt EL84 designs...

Depends... on the drummer....

One of my amps was used a few weeks ago in a club north of here, as is, not
miked, driving a 12" Celestion in a Marshall cab. It was a 3 piece band, the
bass was through a 400 watt Traynor, and the drums were actually miked! The club
was real small, just a bar for maybe 100 people at most.

The sound was quite well balanced after I told them to turn the drums down a
bit... but the guitar was never inaudible.

Going by experience, I'd guess the band was developing around 100 to 110db. I'm
not sure of my amps power, but the EL84 is at 330v, and I suspect the speaker
has a sens of maybe 103db/watt/meter.

I had a video of the gig up on my site but took it down due to space
requirements, but I may put it up elsewhere...

I'd say that for home practicing and/or small gigs a good, old, trusty 5W
Fender Champ 5E1 is the best. It is as simple as it can be, therefore the
player concentrates on his playing skills instead of fiddling with knobs and
switches, and You can make it in a couple of days. Just put a good Alnico
cone in it.

Klipschorn becomes a weapon with 104dB/w/m


I'm using a custom made system for my stereo at home, it's quite old, having
built it and re-built it since the 70s! It was based loosely on various Altek
designs, and each box is 10 cubic feet, a tuned reflex at 40hz. I still have
the original 'Tangerine' driver horns, but I've changed out the 15" woofers, and
added a tweeter crossed over at 10khz. These puppies are 103db/1w/1m.

I used to use a 40 watt stereo amp that I built in the 70s, based on a Tiger
design from SWTPC, and I almost never played it loud enough to register on a
level meter... I had to build a custom LED meter to read levels below 1 watt.

Now I power it with a 200 watt amp, and when people brag to me about their Bose
systems, I treat them to some 'concert' level sound..... Led Zeppelin concert,
that is!!
