Ashley's hi-fi amps

No every Amp Maker customer is a distortion-hungry guitarist. The same valves and components can be turned to more peaceful ends. Smile

"Some time ago I purchased some board from you for my project, at the time you expressed an interest as to what I was making. Well they are finally finished, a pair of replica Leak TL12 Plus amps. And yes they sound as good as they look, well to me anyway!!

"There was a lot of head scratching and drawings on paper before I did anything. Not bad from just a circuit diagram and some picture from a book, 'Firsts in High Fidelity'."

Duncan's JCM clone build

"Thought you would like to see the JCM 800 clone all wired up. works a treat. Just need to set about building a cab or contacting Chris. Thanks for all your help. Here's to the next project!"

Dominic's true stereo guitar combo

"I have now finished my amp, and it sounds and looks amazing. Not sure if you remember my build idea, but it was a stereo guitar amp. As
I don’t have workshop I’ve had to take my time in the build.

   

"I could not believe how loud it is. I use 10-inch speakers Blue Fane @ 100dB. Very sensitive, warm and clear and brake up nice with overdrive. The sound is wide with my stereo guitar FX pedal; somewhere between Stereo and Mono I call it. “Smonno”.

   

"I added lots of extra features, Headphones, Mono send/ Stereo return, Switch able Valve/Diode Rectifier, Push/Push input sensitivity switch, Variable Voltage regulator, Ex Speakers. I also redrew the panels and had them laser cut."

Mike's beautifully built FireFly combo

The FireFly is a great little 1W(ish) amp project that's a very popular project on many guitar forums. But Mike's attention to detail on the design and finish of his is a very special.

   

"Thought you might like to see a few photos of my finished Firefly amp; as ever, it's taken longer than planned but, but has turned out quite well. I say 'my amp', but I must acknowledge the contribution of Andy Gray; he helped answer a number of questions I had during the build process.

"In many ways this hasn't been the easiest of builds. Point-to-point requires considerable thought before applying the soldering iron! The cabinet was also interesting, especially when it came to applying the tolex, but it turned out OK in the end.

"Just to give you an idea of its size the speaker grille on the front is 8-inch in diameter; so I have at last managed to build a 'practice' amp that is actually small enough for my son to carry around. It also sounds pretty good too considering it's a small 8" speaker; it sounds even better when driving a good 12" - amazing how loud it as well.

"By the way, the orange paint in in fact powder coating - gives a really
tough finish, but it's a real so-and-so to scrape off when you need to get a ground connection!"

Paul's 100W Legacy clone

"It is a tight fit. It's a two channel, 100W 4xEL34 head; a Carvin Legacy 1 (Steve Vai signature amp) copy with a few subtle alterations. TAD power transformer, Mercury Magnetics output transformer, Mojotone PCB switcher kit and an FX loop.

"I built the amp from a schematic so had no idea whether it would even go in a small chassis and I believe this is the first ever turret board/hand wired Legacy amp ever made."

Daniel's valve-powered stompbox

"I've attached some photos of an outboard valve pedal I am prototyping, based on the Vox Top Boost pre-amp circuit. I've used 100% Amp Maker parts (except for the case). It sounds very good through a cheap transistor amp, so that was a result, but the case is a bit too compact to be safe, so I need to move it to a lager box before I get it road tested."

Johnny's tweaked Champ build

"I just thought I'd let you know I recently finished an amp based on the tweed Fender Champ (specifically the 5e1 and 5f1 schematics). Without your build documents for your WF-55 I wouldn't have been able to get this amp built. That was my starting point, but I ended up developing from there slightly.

"The main thing was adding a TMB tonestack. I wanted to try and stay close to the character (and voltages) of the '50s Champ though - not copy the later '60s Champ with similar tonestack. So I thought I'd try out a Mosfet buffer after the first stage - doing the job of a cathode follower effectively - to try and prevent the tonestack eating up too much signal. I didn't want to bypass the cathode resistor on the second stage. The preamp is more or less based on the section of the 5f6 Bassman preamp with the cathode follower - except I used a 47k slope resistor instead of a 56k.

"I've been pretty pleased with how this has turned out – I get the warm, rough-edged clean sound I was hoping for. I also really like the impact the Mosfet follower has: it really brings the (much maligned) TMB tone stack to life. It's something I'll certainly use again."

Jake's hi-fi amp

"I ordered a few transformers my college project which was a Hi-Fi valve amplifer. Now the amp is 98% finished, I can send you a couple of photos. Thank you for the great parts and service.

"There is a toroid inside with ventilation above. It uses an ECC83 to split the signal for two outputs. The EL84 power valves are the powr valves.

Jonny's Monster

"Going to attach some shots of my AD30 clone. I'm building an enclosure for it while building the amp. It's getting a coat of Mesa-style tolex at the minute."

Chris' Dr Z-inspired amp

"I have included my amp pics that you can include in gallery if you wish. It's based on a DR Z Route 66 combined with a Dr Z Maz channel with two KT66 output valves. Smile Cab was by Chris. Thanks again for a great service."
