Small orders are hopelessly uneconomic..

MAJ Electronic was founded in 1974 by Michael and Jane Ameson, to service, repair, design and manufacture amplification and associated equipment within the professional music industry. A woodwork department was set up in 1980 to satisfy the need for more and more cabinets. Case and flight case production, an offshoot of this move, began in 1983. So off we jolly well went...

In 1990 old friends Laney Electronics acquired the HH Electronic company of Cambridge and invited Michael to purchase the obsolete stock of this company, and look after the well being of the old HH models. This we did, and still do today. We have continued production of necessary popular replacement pcb's and cosmetic spares for these units, and still produce in house replacement diaphragm assemblies for the CD400/500 compression driver. We NO longer produce the HF200/300 diaphragm assemblies. We provide OFFICIAL worldwide backup, in the form of spares service and technical information, for obsolete Laney and HH products. Many of the original diagrams have been redrawn (for clarity) by Michael.

Here in 2011, MAJ Electronic still have a small but established range of high quality amplification products, headed by our Ameson range of bespoke guitar and bass units, which have stood the test of time and continue to sell well despite the onslaught of imported equipment. We also continue to offer our repair service, and supply spares and service info for HH/Laney and other early British amplification products.

Michael and Jane have a daughter Katherine, who is now 18 and has completed her A level's at King Edwards College. She is studying at Birmingham City University, and is commuting from home. She is pictured above on her PROMS night.

Demonstrations of our amplifiers are now available to see and hear on You Tube. To view, access You Tube, and search for:

We have service manuals for 1970's HH Electronic and older Laney products available in optional .pdf format on CD rom. We also have a huge inventory of schematic diagrams dating back to the early 1960's including rare VOX, Swissecho, Klemt, Farfisa, Meazzi, Sound City, Dan Armstrong, Linear, and many thousands of others. We have recently introduced a service manual covering the Sound City amps from the early 1970's. Included are the Concord, LB 50, PA50, LB 100, LB 120, 120 Slave, LB200.

Requests for single specific circuit diagrams, whether contained in the manuals or not, can be sent via email in .pdf format. The diagrams are free but there is an administration charge of £5 per request for this service, which must be prepaid by Visa, Mastercard. or PayPal. Note we do not accept bank transfers for this service due to the charges. All service manuals are now £9.95 by email, £10.95 (UK) or £15 (overseas) including postage for the book or CD. CD supplied as default. See PAYMENT and POSTAGE page for full details.

PLEASE read this paragraph VERY carefully:

All our manuals are original HH Electronic copyright and all contain good readable digitally cleaned scanned original diagrams as well as descriptions, footswitch data, and fault finding tips written by Michael where applicable. The data and diagrams drawn by anyone at MAJ are copyright to US. We like to give value for money, and in this life you only get what you pay for. There again you might have spotted that already. Oh and if you have possibly downloaded a freebie HH or Laney diagram from the net (saves paying us £5 admin) but then (as usual) need further advice or assistance I suggest - no I insist - you pester them NOT me. I'm rather busy right now. Without wishing to upset any of the prudes, there is another phrase... (2 words, first word sounds Russian, second word is off...)

RE information please ask your technical adviser or engineer to request this as passed information is meaningless unless given to a qualified person who has the knowledge and NECESSARY TEST EQUIPMENT to make use of it. There are no standard or quick fixes to any of these equipments - all problems and faults need to be addressed from basic principles. It's not rocket science, but from my point of view it is difficult to pass on 40+ years experience of the product (or grant an electronic engineering qualification) in a few emails or phone calls. Sorry, back to school you go...

With the best will in the world please understand that this is NOT a forum. Ask me a specific question and I will answer it if I can, but please also understand I simply do not have time to get involved in the 147 bat/ball emails syndrome (as I call it). These mails are usually made from an employers computer when that person has nothing better to do or the gaffer is not looking. Chunter chunter bat ball bat ball. Please understand HE is paying you for your time - which is great until he finds out - mine unfortunately costs money... Thank you. Better still, if you really want an answer to a REAL technical question, call by phone 11 - 2pm and I'll try to help as they should be asleep on Zarg at that time.

Q: Why WITHOUT EXCEPTION do the "147" people mysteriously "go to sleep" when asked to communicate by telephone.

A: No (free to employees) outside line...

Please note questions such as "How many channels does my HH MA100 have" is NOT technical and will be referred to the idiots home or similar institution. Neither is "I have bought an IC100 off eBay and it doesn't work - can you tell me what to change?". Can you BELIEVE 'em?

(My answer would have to be: Your buying habits would be a good start...) DoHHHHHHH.....

We receive many enquiries for foot switches suitable for use with the early HH products and our range of replacement items is listed below.

Before you even need to ask all have the correct switches, cabling, and connectors, and do NOT have status indicators. 3m. cable as standard.

All are hand assembled and wired using modern Laney FS stock as donors. Plug and play. (Doh.. Yes these WILL work.. I made one before...)

All service manuals, diagrams, components and spare parts are sold strictly on the basis that the buyer is qualified to be working on the equipment for which these are supplied, and that he/she also has the necessary technical knowledge to carry out fitment of such parts without causing injury to themselves or others. And that means without asking ME what wires go where, how to fault find it when in reality you haven't got a clue, no test equipment available or maybe don't speaka de Englis (Get a lot of these wallahs..)...

You should also be able to safety test the equipment AFTER repair.

If in doubt, seek LOCAL professional help before you almost certainly ball it, make matters worse, or possibly top yourself. Remember - A little knowledge is DANGEROUS (Forum Fingers beware). Trade customers remember at ALL times that a dead customer is a non paying customer).

! If you are carrying out repairs for other people, professionally or otherwise, I would strongly advise that you take out public liability insurance in respect of that. Doesn't cost a lot, and may save you having to live in a (draughty) tent if you inadvertently roast some poor unfortunate !
