This is my own AC30 it dates from 1963 signed on the top right by its designer the late Dick Denney.

This he did on the occasion of his 80th birthday party on the 24th February 2001 at the sports and leisure  centre Hastings.  He was taken ill on the night, and sadly passed away just a few months later on the 6ht June.     It reads, " To John,   Best wishes,   Dick Denney".   My guess is this is the last   amp he ever signed.

I have owned and gigged this amp for a good number of years now.  It used to belong to Jim Green,  the rhythm guitarist in my old band " The Soundimension" .  He paid £25 for it around 1968, I can vouch for its history since then.

When he had the amp first, it had one leather handle on one end of the amp.  That one was worn through on one end, the other two were missing, the brackets having broken.

I restored the amp as it is now around about 1995

   

I do apologise as this page is now long overdue for updating,  I don't want to up load stuff you can find anywhere on the web, not much point in that as I would like to keep it interesting.  I have loads of images of service work I have done over the past few years, but to up load it all and write up the text takes a huge chunk of my time.  But aI will try and make the effort soon.  Many of you have asked about the S M F amplifier shown in the workshop picture of the home page.  This is an "S M F 30 Watter" ( yes that is its model name) As its name suggests it is a 30 watt class A amp from the Mark Sampson stable of Matchless & Badcat .   S M F stands for" Sonic Machine Factory" .  Just like Matchless & Badcat amps, it is built like the proverbial brick outhouse, over engineered with the massive transformers and top class components.  I think these were made during a spell of, shall we say between jobs, if you get my gist!

Below are some pictures of the home page amplifier, the owner is Dan Anderson, who has since fitted the chassis to a separate cabinet to make a head and 2 X 12 cab.  The original speaker and combo cab has been retained to accept the chassis should Dan chose to return it to its original spec.

                            Front view, the SMF logo has a revolving array of led's which stop when in standby mode.  Front panel removed

                  

3 images of the unusual rear opening flap, attached at the bottom with a piano hinge, and locking side catch  giving the choice of a closed or open back.

                       

    Chassis top view, valves mounted inside.                Neat PCB  5 X 12AX7 & 2 X EL34                              Note the dark grey cathode bias resistors

                 

   The four diodes of the solid state rectifier as fitted to this amplifier.                    A hole has been pre cut for an optional valve rectifier

                                          I will load a picture soon of the chassis mounted in its new cab as it is now.

I have no schematics or any service information for this S M F 30 Watter amplifier.  One thing I will say is, that is gets very hot!  Needs a cooling fan.

 

This is an unusual cast brass logo I removed from a 1961/2 AC30 many years ago.  In all my years in this business, I have never seen another like it.  I wonder if Jennings had a run made, and found they were just too expensive.  I would be interested to know if you may have one, or seen one like it.  This is no home made effort, it is a really professional part.

Have a look at the front and back images.

As you can see the chassis has had some capacitors replaced, works well, but what a shame to have spoiled its vintage looks. 

Amp-Fix to the rescue

From new to old

The new capacitors on the left were cast in the mold, labels were copied from two original caps centre.  On the right are the replica capacitors after casting, waiting for the labels to be fitted.

Above is the mould, made from made from liquid rubber ,the new caps set in the mould, black liquid plastic poured in and left to set.

One of the original labels was scanned and new labels made from the template

The finished product capacitors ready for fitting to the amp

Who would be any the wiser?

Ah now that looks much better doesn't it.  Difficult to show this, and I never thought to take any pictures at the time, but the orangey brown electrolytic's, all have new capacitors inside the original casings, thus maintaining the vintage vibe.
