I have not tried these and am not affiliated but here are a couple of places for tube guitar amp kits. Every studio needs at least one tube guitar amp, right?

If I find others I will add.

Very short answer: great transient response. Quiet. Still good head room compared to many other options. Even not knowing the price its a good pair to have (you want two as they're good on lots of stereo applications). The favorite use at Treelady was distorted electric guitars paired with any ribbon mic or SM 57. I wouldn't have guessed that but that's why we do the tests. An 8-pack of these would be such a SICK live rig that you would need to go to an 8-channel Millennia or Grace to exceed its performance in that regard.

Ach! It appears the DIY500 has been discontinued. Though, the Classic API kits would provide a similar framework for experimenting with opamps and transformers.

Seventh Circle Audio - New B16 Compressor Kit!

Post by SeventhCircle » Wed Oct 05, 2011 2:58 pm

Image

The B16 is an inexpensive, easy to build and easy to use VCA compressor compatible with our CH01/PS03 chassis and power supply. On-board regulators and high voltage supply rails along with a switchable input pad allow the module to cope with input signals as high as +30dBu. Transparent audio quality, program dependent attack and release, and wide gain range make the B16 an extremely useful tool for both tracking and mixing, and the cost is low enough to make it affordable for every channel of your rig. Features include:
  • Very low noise and distortion - beats a dbx 160A by almost 10dB
    Mix control combines direct and compressed signals without a dedicated fx return or mixer channel
    Relay switched 6 dB pad and hard bypass
    Switch selectable hard or soft knee
    Makeup gain provides as much as +/-24dB of adjustment
    Threshold continuously adjustable from -40dBu to +20dBu
    Capable of 60dB of compression
    Program dependent attack and release
    Fully balanced input and output with choice of 3 optional output transformers
Kits available now from $159, assembled modules from $299

Sound Skulptor EQ573, classic equalizer for the Lunchbox 500

Post by JPK » Wed Oct 12, 2011 9:54 am

Sound Skulptor ships the EQ573, an equalizer based on the design and components that were originally used in the Neve 1073 and 1084 modules, that has been adapted to the Lunchbox '500' format.

The EQ573 can be used as a standalone unit but also as an insert, between the input and output stages of the Sound Skulptor MP573 mic pre, recreating the full architecture of the 1073.

Image

Highlights:
- Three bands equalizer and high pass filter
- High shelf EQ: +/-16dB @ 10kHz, 12kHz, 18kHz, 20kHz, 25kHz
- Mid EQ: +/-18dB @ 0.27kHz, 0.36kHz, 0.5kHz, 0.7kHz, 1.1kHz, 1.6kHz, 2.3kHz, 3.2kHz, 4.8kHz, 7.2kHz, 10kHz
- Low shelf EQ: +/-16dB @ 20Hz, 35Hz, 60Hz, 110Hz, 220Hz
- High pass filter: -18dB/octave @ 25Hz, 45Hz, 70Hz, 160Hz, 360Hz
- Additional frequencies in all bands
- 3 Q values for the mid EQ (1073, 1084 and 1084-Hi)
- Single ended, class A circuit
- Carnhill inductors
- Available assembled or as a full kit (everything included)

This product is a new addition to our range of DIY kits. The DIY approach on these products makes them affordable to most - without compromising on quality. The skills needed to build the kit are basic, thanks to careful design and to the very detailed instructions. Of course, the products are also available fully assembled for the non-technicians.

Seventh Circle Audio A12b Preamp

Post by SeventhCircle » Tue Oct 18, 2011 2:44 pm

Image

A12b Microphone Preamp

The A12b is a simple, single stage preamp module that evokes classic American designs of the early '70s. Using exactly the same circuit as our modular SC25 op-amp, the A12b offers all of the performance of our standard A12 at a lower price and without the complication of assembling a kit. The A12b sounds fantastic with rock drums and electric guitars, but is versatile enough to be used in virtually any application.
  • * High Gain of up to 70dB, including the voltage step-up provided by the transformers.
    * Tremendous Headroom of over +30dB into 600 ohm loads.
    * Stepped Gain Control from a 12 position Grayhill switch provides accurate and repeatable gain settings in 5dB steps from 15dB to 70dB.
    * Gain Trim by a high quality Bourns panel control enables up to 6dB of cut at any gain setting allowing fine adjustment between steps.
    * Sealed Gold Plated Toggle Switches for phase and phantom
    * Slow-Rise Buffered Phantom Power Switching minimizes pops and thumps.
    * Neutrik XLR Connectors provide a professional interface and and eliminate point to point wiring.
    * CineMag Transformers are the highest quality, made in the USA.
    * 20dB Pad on board, post output transformer, jumper switched.
$299 as shown

Order with our 2RU chassis, 80W power supply, and internal wiring harness for a package price of $599!

Also check out the new low prices on standard A12 kits and assembled modules!

T15 in use

Post by ghaines » Mon Mar 05, 2012 12:02 pm

Over the weekend we had a big drum session for an upcoming Ben Shannon CD. For drum overheads they had a pair of 1970's KM81's borrowed from http://www.seanmcdonald.com/fr_home.cfm (a wonderful Pittsburgh engineer). For the preamps, they had many choices, including API, Neve (current UK make), Neve 1081 (vintage), Millennia (FET and Mullard tubes), a bunch of others and the T15....

Guess who was selected?

Yep. The T15s. They were the right preamp in this situation. Now, we had been using it on guitar, and this drummer was not beating the snot out of his cymbals. It was more of a classic rock thing, but the T15 + the vintage Neumann's were the bomb.

There you go.

The Austin Ribbon Mic is really really really nice. The top end is extended and smooth. Look for a review.

Also in the build stage http://www.hairballaudio.com/Hairball Audio Lola 500 series pre-amps and a nice piece of Tube Gear from DRIP electronics http://www.dripelectronics.com/

The LINE2AMP reamping box has been the most popular kit on DIY Recording Equipment since it's introduction in 2011. The kit has been continually refined since then to improve the quality and ease of construction. I've heard from many customers who have successfully built it in under an hour. The box is based around a USA-wound Edcor transformer. Sonically, it's practically transparent and indistinguishable from $100+ reampers.

Finally, it's cheap! $39.95 for the full kit.

A new kit from Sound Skulptor

Post by JPK » Wed Mar 20, 2013 3:22 am

Sound Skulptor ships the MP 5.12, a mic Preamplifier for the Lunchbox

Image

The MP 5.12 is a microphone preamplifier based on one discrete Op-Amp, one Cinemag input transformer and one Cinemag output transformer.

It delivers what was called the "LA sound", popularised by the famous American consoles of the 70's : the punchy midrange and tight bass tone of the iron. The MP 5.12 is great on drums, electric instruments and generally all close miked sources.

This product is a new addition to the Sound Skulptor range of DIY kits. The DIY approach on these products makes them affordable to most - without compromising on quality. The skills needed to build the kit are basic, thanks to careful design and to the very detailed instructions. Of course, the products are also available fully assembled for the non-technicians.

Highlights:
- Discrete Op-Amp design, pin compatible with the API* 2520
- Original Cinemag transformers on input and output
- SK25 low noise, class A discrete Op-Amp
- 70 dB of gain
- Variable output pad for those who like to drive it hot
- Fet DI input, relay switched, the signal passes through the input transformer
- Easy build
- Available assembled or as a full kit (everything included)

For more information, visit our web site at http://www.soundskulptor.com/uk/mp512.html

After many requests, we're happy to introduce the rugged, compact, convenient, and affordable OneShot chassis. Designed primarily for easy tabletop operation, the OneShot can also be rack mounted. Just remove the feet and screw up to four OneShot chassis directly to a Raxxess UNS-1 as shown. No other hardware required!

Image

Features include:
? Discrete, class-A instrument DI with high-impedance JFET input
? Separate balanced DI output
? DI output drives preamp input transformer for maximum ?color?
? Relay-switched 20dB input pad
? Relay-switched microphone input impedance
? Rugged 18 gauge steel and aluminum construction
? Laser-engraved front panel
? External 24VAC power supply for minimum noise and low cost
? Accommodates any Seventh Circle Audio module
? Made in USA

Prices start at $149 for a separate kit and go down from there when combined with preamp modules. Look for pricing to be up on the site by April 1, no fooling.
