This is my own version of a classic preamp, popular in the 70s and still popular today. It's not a clone since I'm using a totally different signal path and design, and different input and output transformers. But the sound nevertheless is awesome.  Big and beefy with lots of transformer mojo goodness.

August 2008: SC-1 mentioned in MIX Magazine Review
SC-1 Mic Preamp was used in the field test review of Avant Electronics Avanton CK-40 Stereo Mic. Read more about it in the MIX Magazine August 2008 issue.

May 2008: SC-1 mentioned in MIX Magazine Review
Check out Barry Rudolph's review of a Peluso 22 47SE Tube Microphone and IK Multimedia Advanced Room Correction Software in MIX Magazine May 2008 issue. He used the SC-1 Mic Preamp in evaluating both products. Check out his website, http://www.barryrudolph.com, for more product reviews from this L.A. based recording engineer/producer/gear reviewer.

I have finished your kit and it sounds fine and I'll be using it in sessions soon. Anyway the pre-amps both worked perfectly from the first time and seem to sound very good. I've already had questions about buying more of these kits 'wholesale' in numbers. Good Luck with your kit. It's a solid product and I had fun building it. - Barry Rudolph, Recording Engineer/Producer/Gear Reviewer - http://www.barryrudolph.com

You can also adapt this for use in your own DIY preamp or project. See the Assembly Guide/Instructions for the block diagram to see how it sits "in-between" your preamp and XLR jacks.

Features:

VU Meter Kit


Qty Available: IN STOCK
Lead Time*: 2-3 days

They're back. These little VU meters seem popular with the DIY crowd so I'm putting them back online.  They can be powered with anywhere from 6V to 24V. An internal +18V regulator keeps the device protected for use with higher voltage supplies. You can change the direction of the LED meter movement by using simple jumpers. There is also an on-board trimmer to make adjustment easy.

NOTE: If you'll be ordering the VU Meter kits with any of my other kits, EMAIL ME so I can give you free shipping on the VU Meters. I'll send you a Paypal invoice with the discounted shipping. Otherwise, normal shipping fee applies.

PSU-CABLE4 is a polarized 4-pin/conductor wire assembly with Male and Female mating connectors. The mating connectors are Black nylons with clip releases. #22AWG wire, 12 inches in length.

USe the Female side of the connector to connect to your PSU-1848/2448. That way, the terminals carrying power are not exposed. Use the Male side of the connector to connect to your SC-1 preamp. I personally use the following color code convention:

BLACK - Connect to GND
YELLOW - Connect to +48V
RED - Connect to +18V
GREEN - Connect to -18V

SC-KNOBS2

These are the knobs I use on the SC-1 preamp. There is a brass set screw so you can use this knob on 1/4" shaft. I think it's a pretty cool looking knob. The finish is smooth, and the feel is great. It doesn't feel like "DIY", if you know what I mean.

I am sorry, but these knobs are NOT made of virgin forest exotic wood, or dipped in C37 lacquer and costs $500.  I think you're on the wrong website if you're looking for that kind of stuff here. :)

Ordering Instructions and Terms of Sale: READ THIS!

 

All kits will ship within 24-48 hours (1-2 business days) after payment is received if stock is available. This is not a rock-solid guarantee but we strive for this. Other factors beyond our control may delay shipments beyond 2 business days. But this is very rare.

NO PARTIAL SHIPMENTS. When we receive the component/part from the supplier, the number of kits available and lead time will be updated. Please note, we can't ship your kit if there is a missing part. We do not do partial kit shipments.

*LEAD TIME. Our kits require several components that come from multiple suppliers. If certain components required in the kit are out-of-stock, the lead time will reflect how many days or weeks it will take for the supplier to ship the component/part. This is just an estimate and not a guaranteed time. Pre-assembled kits will have extra lead-time, as we assemble, build and test your kits.

ALL ORDERS ARE FIRST COME, FIRST SERVE. If you place an order when there is a lead time (i.e. a component/part required is out of stock), you'll be the first to receive the kit when the part becomes available again.

PAYPAL ONLY. You can pay by credit card via Paypal. We only accept payment via Paypal. No bank transfers, money order, or check payments, not unless this is done through PayPal. Note: You'll see "Web10Hosting" as the name of our business Paypal account.

ORDERS ARE PAID IN FULL AND IN ADVANCE. Your Paypal or credit card will be charged when you place your order, NOT when we ship the order. IF THIS IS GOING TO BE A PROBLEM FOR YOU, DO NOT PLACE AN ORDER. Wait until the kit becomes available again and the lead time is 0 days. But you'll have to wait at the end of the line. All orders are first-come, first serve.

Quantity available shown on this webpage is not updated in real-time. But we'll update this data as often as possible.

INTERNATIONAL BUYERS will be responsible for VAT and custom fees, if any.

WE WILL ALWAYS BE TRUTHFUL IN OUR DECLARATION ON CUSTOM FORMS. We will not lie, mark it as a gift, sample, or lower the stated value of the kit. Don't even ask. If this is unacceptable for you, DO NOT PLACE AN ORDER.

SHIPPING AND HANDLING. These fees cover the actual shipping cost, plus cost of boxing, packaging, bagging, sorting, labeling each and every component in the kit. U.S Orders over $50 will be shipped via Fedex or UPS Ground. We'll email you your tracking number once we have that information. U.S. Orders below $50 will be shipped via USPS Priority or First-Class Mail. International orders will be shipped via US Postal Service. If you want UPS or Fedex for INTERNATIONAL Shipping, let us know. But you'll have to pay extra for shipping costs. They're usually around $120 for UPS/Fedex International Shipping. Exact pricing varies depending on your country/location.

ADDRESS REROUTE. We will only ship to the address listed in your PayPal account. Any Address change requests from the customer before the package has shipped out will be decided on a case-by-case basis. Any address correction or reroute AFTER the package has shipped is decided on a case-by-case basis, and subject to a $20 charge.
