the lava lamps are another obsession of mine ive got about 65 in all......i actually repair those as well...
I'm a little obsessed with them as well. I bought a few from Goodwill for $4 each. One looks like yours is my favorite one, except it's probably about 2/3 height of yours.

Show off!!
That's real obsession. I just got started. Are all those from years of collection, or buying used or new?
most i have bought used,ive been collecting for about 5 years...the most expensive one i own is the yellow mathmos next to my tv 100.00 from england..
Do you have a source for parts? I have one (standard size, fairly recent production) that needs a cap and a switch.
Jeez.......780's and Lava Lamps.....What's next.....Water Pipes, insense holders, Love beads??????? 
Inna-gadda-da-vida while stoked???? :thmbsp: Hmmm sounds like the thing to do during the snow storm today
Personally I like the x90's over the X80's. Just gotta have some MORE contrast than what the x80's have on the meters.

if you can try to just buy a used american made lavabrand or lava lite sometime in the early 90s they closed down the chicago factory and sent work overseas and the quality went down the drain (cloudy globes,crappy lava flow on and on) the american made models are definitly superior the lava actually flows and stretches as opposed to a bunch of balls or a large ball that just floats up and down..... also check out oozinggoo.com theres a wealth of info on there....
Pioneer SX-780 filter caps
New to AK, my fist post. hope this works. Im working on recapping my Pioneer SX-780. i have all the caps except 8000uf filter cap. im about 25% complete. But haven't got to the filter caps. Looks like they have three prongs. Does anyone know the replacement cap I can use for the 8000uf 50v filter caps, and where i can get them? i would appreciate any help

Although this is Dowey's thread. I'll provide the pic of some mod done to the main cap to provide a little more freedom of choices. The original main cap is 15mm lead spacing where it's too hard or impossible to find new for 8000uf 50v. So I ordered Nichicon KG 8200uf 50v and I am determined to use that. That was the ONLY of that kind I wanted to use. It's 35mm diameter with 10mm lead spacing where the original is 30mm diameter with 15mm lead spacing with a dummy lead that is 10mm lead spacing from either positive and negative. The mod is done by removing all the pins in the positive and negative side of the boards and solder the wires directly to the pads. I inserted the new caps using one positive and dummy pads on one cap, then put jumper from dummy pad to the ground pad. I insert another cap using one negative and dummy pads, then put jumper from the dummy pad to ground pad. Have been using it like that everyday for several months.
Welcome to AK. Next time, you might want to start your own thread. :thmbsp:

Unfortunately, it's a much more recent model. I'll have to keep an eye out for an older one, though I do rather like the "ball" effect, especially when it gets stretchy and oblong.
I also have a non-lava-brand light that I'm quite fond of - it's a Marvin the Martian rocketship with red lava.
This is a great trick, I’m going to give it a whirl!
But this post got buried in an odd thread. Any admins out there that could move this to its own so it’s searchable?
Ok I used this and it worked out fine so far.Although, my same SX-780 receiver I posted about years ago is still being used to this day. I would suggest using thicker jumper wire from dummy pad to appropriate polarity. Of course, I haven't done so on mine. It's working fine but still recommend.
Let me ask you all if my hack jumper will work out long term or have i done something i might regret…. I did not have any jumper material so I cut a couple of 3/4” long pieces of 14 awg solid copper ground wire out of 14/2 house wire. I figured it would handle the current and is pure copper. It tinned up and seems to be working well.
I had to snip the pins off at the board level to get the capacitors to fit in as they are slightly off the original center point.
Thanks, that makes me feel better.My caps are off center as well. Had to turn them a little to line up with one polarity and a dummy pad. I physically removed most of the pins on that board and wired from underneath. 14 gauge is WAY PLENTY!! You're fine.
No problem. 780 is a fine receiver. Been having mine since late 2007. It's going nowhere. Can't believe it that I had it for almost 20 years. I plan to rebuild the power packs with discreets. They're aftermarket junks. Hopefully, will finish this month. Maybe, I will fix that jumper while I'm at it.
