Schematics

SCHEMATICS LIST | BEFORE YOU ORDER | ORDERING | FEES & CHARGES | PAYMENT

After 25 years, I have collected a huge number of schematics for musical electronic equipment, both hard copy and electronic files.

In addition to our current inventory, we also have outside resources at our disposal that we may use to obtain even more materials than are listed below...or to search for special order items.

There are thousands of schematics here for guitar and bass amps, power amps, mixers, P.A. systems, a number of effects, some electric pianos, some electric guitar & bass wiring diagrams...and more.

So many...that I have not had time to gather them into one location or put them into database form for web purposes.

As many of these items are still available direct from the original manufacturer, or from other sources...I have not decided on how extensive of a list that I will be posting.  For the moment,
I have posted a partial list of our schematic inventory by manufacturer only.  This list will be added to, as new items are uncovered.

Our main business is repair, modification and custom design of musical electronic equipment.  Time spent researching these items, is time spent away from the bench.  We charge a minimum $20 Research Labor Fee per item.  We offer these as an aid to repair technicians who have not been able to locate them from other sources.*

  Before You Order 

We Charge A Minimum $20 Research Labor Fee Per Schematic

Before inquiring about a particular schematic or other materials, you should check with all other resources available to you.  Many schematics and manuals are still available direct from the original manufacturer or other sources.  Do Your Research.

If you have checked all of your sources and cannot find the item that you need, you may contact us.  We will search our inventory and resources, and let you know if the particular schematic or materials are available.

 

  Ordering 

You may contact us via email or by telephone during normal business hours to inquire about available schematics and materials.*

Please have information as to the particular Brand, Model, Model Number and approximate age or era of the circuit that you need.

We only provide materials for Standard Manufactured musical electronic equipment, both, current production and those no longer being made.  We charge a minimum $20 Research Labor Fee per schematic.  Multiple page items will incur extra cost and be billed by request.

Items that are in a large format will be scanned in sections to the best of our ability.  The large format item segments will total the complete schematic, and will be legible for repair purposes. WE ARE TECHNICIANS...these items will not be scanned by an office employee or someone with no knowledge of electronic circuits.

A small number of our items are old, original and perhaps not the best quality.  Most are fine for repair and restoration purposes.  We will advise if a copy is poor or not very legible...and let you decide.

A partial list of our current manufacturer inventory is shown above.  We also have access to many other manufacturers and models not listed.  Feel free to contact us if you do not see a particular item listed.

  • We Do Not Provide Schematics Of Custom Designs Or Modifications,
    whether it be our own design...or those of others.
  • We do not provide schematics for Boutique Amp circuits.

We Design And Build Custom Amplifiers And Circuits
We can build a Custom Designed Circuit for you

  • We are not it the DIY Novice Hobbyist business, and do not provide technical assistance or guidance for the casual experimenter.
  • These materials are offered to aid in the repair and restoration of production model units, by qualified electronics repair professionals.

          *These items are offered for repair and restoration purposes only.
By ordering an item you agree that the material provided will not be used for any illegal purpose, or to infringe upon any existing right covered by Patent, Trademark, Copyright or other legally Registered Use.  Dangerous or lethal voltages may be present in many of these circuits.   Repairs should only be attempted by a qualified electronics technician.


 

  Fees & Charges 

We Charge A Minimum $20 Research Labor Fee Per Schematic

This fee is for our time and effort researching, scanning and emailing you the item that you request.  There is no charge or cost for the schematic.

Individual schematics, service manuals and other materials involving more than two pages will incur extra charges, and will be billed per request.

We prefer to scan and email technical items and do not normally send hard copies.  To have hard copies made and arrange for postal delivery, involves a large amount of time...and will incur considerable extra expense.
We charge $40 per hour for our technical services...whether it is at the bench...or stuck in L.A. traffic, trying to get to the post office.  We suggest scanning and electronic delivery for these items.


 

  Payment 

Contact Us to place an order and request our mailing address

Payment is to be made by US Postal or Bank Money Order.  You may send cash payment if you prefer...but we suggest sending any cash payment via USPS Priority Mail with a Delivery Confirmation Tracking Number. We do not accept personal checks or drafts on other accounts.

Online Payments can be made using c2it by Citibank and AOL Quick Cash services.  Please see our Ordering Information department for more details on Online Payments and International Orders.

We will email you when your payment has arrived and send the requested materials within 24 hours.
