Re: Jansen Owner Club
The problem with this thread, even though it is spelt differently, it keeps making me day dream about joining a slightly different owners club:
The older I get, the more disappointed in myself I become.

Re: Jansen Owner Club
Ahead of you on that one, the one in my pic is also an Interceptor R. Not supercharged in this case, but I prefer the colour. Plus it's relatively paltry 480hp is probably still enough for a bit of fun.

Re: Jansen Owner Club
Let us know how you go. I could chat to John G in Hamilton...see if he could help out. He’s reversed engineered some of my booteek stuff before.jvpp wrote:Spoke to Clarry and he confirms they are rare and hasn't got any diagram. The good thing is he has repaired a couple and says the circuit is very simple.Slowy wrote:4-12s are rare. I've only ever seen 2. Consider they were made in 1964, just as full stacks were taking over the world. Poor little fellas never stood a chance.jvpp wrote:
Yes browsed that site a while ago for a 6/20 diagram. Could not find it there and it does not mention the 4/12.
Will call Simon tomorrow and if no luck I am offering to do the exploratory surgery... Perhaps a dedicated thread is warranted rather than annoying EB?

I'd happily trace this out. I've documented a lot of Gunns and Holdens over the yearsSlowy wrote:If there is someone who can do it, I'd make my amp available for non invasive mapping. I think it would be a cool project to be involved with.bender wrote:Yeah, that’s an amp worth cloning! Ask Clarry?jvpp wrote:Now that i have heard that 4/12 I wouldnt mind getting or making one. Any cicuit diagrams yous guys have?

Re: Jansen Owner Club
Is there anything special in a Jansen preamp versus, say a Fender? (Thinking about MTS blackface module options)Optical wrote:I'd happily trace this out.

Re: Jansen Owner Club
Dunno, Ive got two Jansens (or bits of...) but both were trashed when I got them.
There is a very strong chance of them being a fender circuit or something incredibly close to. Usually a bassman or JTM type thing but the transformers are often quite different as they were usually locally made radio/HiFi spec which can change the tone and dynamics a bit. Also 50+ year old capacitors are typically fucked which also change the tone (compared to if it were new), meaning you have to measure the components rather then read the labels to know exactly what's going on.

Re: Jansen Owner Club
I've got a Jansen Lil' Dazzler 30 watt solid state thing lurking in my amp archives, circa 1970's. One of my older specimens, may take a photo.

Re: Jansen Owner Club
Had a few Jansens over the last 40 years. Still got this renovated 1964 Bassman 50 which I salvaged from a dumpster 3 years ago and fixed up. I managed to re-use most of the mustard caps. (Note the 12V heater wiring)

Re: Jansen Owner Club
So Simon doesn't have the circuit diagram and is reluctant to dig into his paper mountain of old amp docs. Will PM you Slowy re next step.
When faced with quality, I recognise it every time.

Re: Jansen Owner Club
At least you didn't ask him for a one page schematic and he sold you an encyclopedia on tube amp building!

For the next step, it seems my amp is going visiting. It would be more fun for you if the speaker cab tagged along?jvpp wrote:So Simon doesn't have the circuit diagram and is reluctant to dig into his paper mountain of old amp docs. Will PM you Slowy re next step.
