Sorry to say it's not a simple rewire. The MM pick-up and pre-amp were designed as an integral assembly. The MM pre-amp has a differential input stage to allow it to sum the signal and cancel any noise. It also has a switched resistor ladder to equalise the gain for each configuration, not easy to replicate. I did what you are attempting to do about 8 years ago. Firstly you have to rewire the pickup to have six wires so that each coil can be accessed independently. This was how I did the switching with a 4-pole 3-way switch. Best of luck.

[quote name='Happy Jack' timestamp='1326309552' post='1495337'] That's really neat, Dave. Where did you find the rack-ears for the GK amp? And how does that design work? [/quote] 1U and 2U rack ears are readily available from a number of sources. For the GK it was a case of drilling fixing holes in the rack ears to line-up with the tapped holes in the GK, finding some spacers of the right internal diameter and cutting them to length, then getting the right size screws of the right length and finally making it all fit. Similar process for the Boss and the dbx. You ask how does it work? I plug it into the speakers, connect the National Grid interface, plug in the bass and it makes a noise.

I pcked up a Boss TU-50 from here and mounted it with a dbx compressor and a GK MB200 is a half-rack case I giot from Ebay. One day I'm going transplant it into a 1/2 rack size aluminium flightcase.

Make a cable to run the two cabs in series to make 16-ohms, and Robert is your father's brother.

Partial result. £689 if bought in the shop, however still too much.

Interesting that they also have it on their web site and in the store at the same price. By my reckoning the Ebay Sellers fee and Paypal fees come to about £65. I wonder what they would want for collect and pay cash. Maybe I'll ask.

for a used 90s Japanese Fretless Jazz? [url="http://www.ebay.co.uk/itm/Fender-Japanese-Fretless-Jazz-Bass-Olympic-White-/310334562740?pt=UK_Musical_Instruments_Guitars_CV&hash=item484161a1b4"]http://www.ebay.co.u...=item484161a1b4[/url] I saw a similar one go recently for £400.

Greg bought the Godin A5 Fretless from me. He travelled down from London by train and we met at Guildford Station to conduct the deal at the time agreed and without a hitch.

Happy New Year to all on Basschat.

Wow that stirred up a bit of interest. I was in the process of rewiring it a few years ago. The power amp side is all done but not tested. The transformers and choke are in excellent condition and it has all new caps. I'll dig it out of the garage tomorrow.

[quote name='pete.young' timestamp='1325092497' post='1479780'] If OBBM is still reading this thread, I for one would like to know what he tried, and whether it worked or not. [/quote] Pete, I ended up with two amps neither of which I have had a chance to try seriously yet due to lack of time. The first was an Ashdown LB30, the other is a Hayden MoFo 55, 55-watts from a pair of 6550. When I get an opportunity I'm going to try them with the Berg AE212 however the Berg is 4-ohms and the MoFo only has taps for 8 and 16-ohms. I tried it with a single 1 x12 and it was promising. My original idea was to modify the tone stack of the MoFo55 so it was more suited to bass however I'm no longer convinced that it would be a good idea, also the output transformer look a bit small compared to some of my other valve chassis. I've got the MoFo up for sale in my Ebay store so if it sells the it will go. I shall probably sell the LB as well, plus the parts of the Sound City 200 and see if I can raise some cash for a Hiwatt.

[quote name='JTUK' timestamp='1324560097' post='1475582'] Saw it,,,what I want to know is...how come it is acceptable for the camera man to have his own copies stashed at home... and he says he has others..!! Homework...??? [/quote] I've known John Henshall, the cameraman concerned, for many many years. While he was at the BBC he started developing optical effects - special lenses - of which the Fish Eye used in this clip was one of his first. He eventually left the BBC and started his own company. He obtained a copy of the tape as the effect was his creation and no doubt he did not charge the BBC of the use of the lense so a copy of that sequence was fair recompense. Videotape for 2-inch bradcast VTRs was very expensive and someone in BBC management decided that they could save money by wiping and re-using tapes. Thousands of hours of unique television got destroyed in this process. It will be interesting to see what else he has hidden away. One of our local jammers spends some of his spare time researching and tracking down lost footage from that era. This is one of his finds, so thanks Ray.

[quote name='umph' timestamp='1324554650' post='1475470'] what are you after? [/quote] Specifically the circuit of my AD200B Mk 3 but I feel that putting schematics into the book would add so much more value and would help justify that outrageous price.

Nope still too much. Now if it had all the schematics as well then that would be different matter.

Steve Ryder has been making custom basses for years. Seeing as this show was in 2008 I doubt that it's a Sue Ryder bass he's playing, probably an upmarket custom jobby.
