Yes. Salvage has a proprietary method of creating colored bursts on tweed. They have a Bourbon Burst, a Cherry Burst, and a Zombie Burst (dirtier version of the Bourbon Burst). Mine is the Bourbon Burst. #salvagecustom

finally finished my supro 1616t clone.

Hello Tomasha,

It's me or there is a small speaker put on the floor of the cabinet ? What for ?

A+!

[thomasha]

The OT I had was 5k to 4 ohms, and the speaker 8 ohms so I tried it with the small speaker for impedance matching.

When the new OT arrives I will remove it.

Ah, OK, I see. I also have some OPT issues : I am planning to change the OPT of my COMET (Hammond 1760C) for a bigger one which respects the basses better (Hammond 125BSE).

A+!

My interest in DIY audio started with speaker cabs. I have come to favour transmission lines and dislike bass reflex immensely.

My fullrange studio monitors (the prototype natural pair for my house/my wife, white pair for my studio and red pair for my little bro):





These are designed to be wall or soffit mounted making them ideal for use in smaller rooms.  That's only a 4" driver but due to the TL loading and wall placement there is no shortage of bass.  Amazing stereo imaging due to complete lack of crossover and point source of sound.


I also built what started as a 2x12 lead/bass cab (a bit smaller face than a 4x12, but deeper) but was sawn into 2 1x12s when I realised it wouldn't fit into my then bass player's Civic.  It's much more usefull that way - keep one at the studio and one at home:





They have the midrange clarity and detail of an open back with the bass response of a sealed or even horn (yet still not too boomy when used with a bucker equipped guitar).  I like the one with the Marsland (Jensenish) for guitar and a JBL or EV for bass.  It'll take any guitar speaker with an Fs of 65-85 (which is 99% of guitar speakers) and have enough low end extension for bass use (gotta love those TLs). Maybe even a wider range if you're willing to play with the stuffing.

And in a moment of poor judgement I built this monstrosity (loaded with 8x10" vintage pre-celestion Rola alnico magnet woofers):





That's one of the Lead/Bass cabs with the grille on on the left in the last pic... and the middle cab is not a Traynor (came to me that way, which is why I got it as cheap as I did) but actually a Musicman 115RH - a very nice cab indeed (reflex horn).  They greatly benefit from replacing the stock Eminence stamped frame driver with an EV cast frame one (there was an option for a factory upgrade; pity the fool who didn't take it).

Somehow forgot my latest creation: a Transmission Line loaded active boom box style portable speaker:









I used a PAM8610-based digital amp board, hacked it up a bit (flimsy jacks taken off board; added a battery cage etc) and made a flanged enclosure out of some sheet aluminum I had laying about.

Granny Gremlin, that's awesome!

[thomasha]

Made a small boom box for a friend,
I used some ebay boards for the amp, charger and bluetooth module.




Cheers,
Thomas

This is a Marshall TMB MV 18 watt clone made using a kit. I made a few mods:
- replaced the pots with Alphas
- added a switch to choose between the valve/tube rectifier and a solid state rectifier
- removed the second input from the second circuit
- made my own face plates

[alanp]

... that wiring is really nice, almost Hiwatt

[bloxstompboxes]

Excellent work Peter! I especially like the white on chrome. Very elegant looking.

[davent]

Beauiful, beautiful job Peter! Gonna be loud!

Trinity kit?
dave

[peterg]

Thanks guys.

Dave. I picked up the kit at A1;

http://www.a1parts.ca/Tube%20Amplifier%20Kit%20&%20Accessories.htm

It's from Mabel Audio:

Alan. Good catch. Hiwatt was my inspiration for the wiring.

[davent]

Thanks Peter.

Question about A1, when i've taken a website shopping cart through to checkout part prices show up as $US. When shopping in-store do the prices reflect this or for example, was your amp actually $399cdn? Haven't yet come across anything on the website stating which dollar is used for website pricing, prior to checkout.

dave

ed1. And i go back to the page and there's the answer, duh!

ed2. Had been quite some time since i'd tried an order so either i'm dense and missed this dollar info or they've updated the website. Really good prices on Hammond transformers.

[peterg]

Dave. Yes the kit was $399 CAD. I've only picked up product at the store - never online.

[pickdropper]

Wow Peter, that build is amazing.  From wiring to chassis design, it's fantastic.

[peterg]

Thank you Pickdropper

[deadastronaut]

yeah classy amp man....is that an etch on the faceplates?...

i just etched a 19inch rack, it was a nightmare, splitting the image lengthwise in half ,
and making a box long enough to etch it in.....grief..

[peterg]

Thanks Rob. The face and back plates are etched. I had to split the front plate into 3 sections to keep the channel control outlines whole. After applying the toner I masked the surface, except for areas to be etched, with masking tape. The plates where laid flat and the etchant was sponged on.

[deadastronaut]

cool, thought so,

yeah its a lot of work, but the results in the end are well worth it..looks tasty.
