Very nice looking FireFly there.

This is an old amp that i took out of a reel to reel that was not longer working using 2 of the 3 12ax7 the output tube is a 6AQ5A. Still need to replace the filter cap but it works and sounds great maxed.

Might be small, and might be solid state, but it's still a guitar amp...and 20 watts too!

It's Taylor's Tiny Giant Amp from musicpcb.com. Great sounding little guy:

I was, but then I thought "I'll never take it out of my house, and it probably weighs about 5 lbs... anywhere I need to move it to, I'll just pick it up and carry it." And thats what I do.

And that's actually not tolex; it's some vinyl 'marine' fabric I got at the fabric store. The look is similar, but it's softer to the touch.

Can someone tell me what is the name of this particular type of PCB/board?

Not the name of the circuit but, the actual name of the board style/material. Its not vero, or regular PCB. It has the posts on the sides of the board to solder point-to-point.

Thanks

It's a turret board.

Thanks Gabriel. I dont use them personally but, I recently came across a few brand new TURRET BOARDS and had no idea what they were

It's a homemade turret board using plexi-glass (I think) and rivets. Does the job really well!

I'm trying terminal strips for the next one though...

Hi, my Vox V212BN, freshly comboized

Find more pics here..

Cheers, T.

John Lyons · « **Reply #154 on:** May 15, 2011, 02:36:31 AM »

Can we get some better pics Thomeeque?

(a joke)
Nice work!! Can you tell us more about the amplifier in there?
What is it actually?

Great job.

Thanks, John!!

Conceptually it is one channel solid state 35W/16Ω (50W/8Ω) guitar amp with guitar level input, Bright boost switch, 3-band EQ, Gain and (Master) Volume controls and very simple "tube-amp modelling" (just simple soft-clipping applied at the pre-amp out). There is only "Standby" (Mute) switch, no power switch (it significantly simplifies lethal wiring and first tests show no drawbacks so far, quiescent load from mains is cca 6W), dual-color LED indicates actual state (RED = standby, GREEN = on).

Primary goal was to get transparent PA for the signal already completely cooked by my pedalboard, but it is able to be overdriven to blues/rock kind of distortion in simple guitar->cable->amp configuration.

As an pre-amp I have used just very slightly modified Rod Elliott's pre-amp from his 100W Guitar Amplifier Mk II project (I have removed R2, LO in, VR4, R10 and whole output buffer and I have replaced R12 by A100k "GAIN" pot.. and bridged Bright switch by 100k resistor to make it's switching popless.. and used 7815/7915 pair for ±15VDC regulation).

As an power amp I have used LM3886 based kit.

There are few threads related:

LM3886: Vs = ±35VDC, Load = 16Ω, Pout = 35W - right?
Solid-state guitar combo amp: using speaker-forced airflow for cooling heatsink
optimal toroidal transformer mounting
Old CPU-cooler as an LM3886 heat-sink

I'm still testing it (my biggest concerns are LM3886 cooling and danger of parasite sound effects caused by stuff added inside), so far I've used it only at one rehearsal and it seemed OK (but it was a cool day and I could not go to the highest volume levels), today is next rehearsal and at Wednesday we have a gig (and that's where it all will go wrong

.. but I'll have some backup there).

Cheers, T.

Very nice, thanks for the details.

my first amp :3

Inspired by old soviet solid state transformer design. Totally recycled btw

some guts:

now working on power supply, more pics soon.

Wow, that's really cool.

5E3 circuit in an old webcor cabinet. 10" weber alnico.
point to point with tag strips, two chassis's, (upper
and lower), hand made.
