Its a monstah!

I got this GE Talaria MP projector some time ago but was not able to access it because of COVID-19. I think this projector was built around 1997, has a resolution of 1024x1280 (I guess they mean 1280x1024 but it is written the other way around in the documentation?!) and 8000 lumens.

Unfortunately all boards do have a ton of tantalum capacitors on them and one started to burn when i started the projector 

I've replaced the capacitor but i guess the next one will blow on the next try to power it up. I have the service manual with all schematics and a box with some spare parts for this thing.

I had to remove some pictures from the post because of the 5M limit.

I don't care what it does, those are some good looking guts.

I got the Talaria powered up today without smoke, after preheating for about 40min i was able to switch on the lamp but it does only project garbled stuff, i guess the Repair section of this forum is better for this topic, i will post the next updates there.

Wow - that's a huge number of tuning slug adjustments for a projector!  Must be a bear to align...

Amazing score and 11A@230V! Quite the powerhog, considering that you needed one for each color (according to the Wikipedia article you linked).

It's amazing how technology evolved.

Don't forget, this thing has 8000 lumens, after a quick search a modern 10000 lumen laser DLP projector seems to use about 1300w, i did not find one with 8000 lumen, the Talaria is rated for 1750w. I left the service manual with the projector and do not have it at home, i think the lamp is rated for 1000w and the heating for the oil inside the tube seems to use a ton of energy too...

Nice, I found a good cheat for avoiding customs import duties for my customers in the EU/UK - I declare the products as "commercial samples" and the description as "prototype adapters". Luckily as my products are all hand soldered using TH parts and they use Prototype HASL PCB's, if customs were to inspect the goods they'll not find any reason to disagree.

Yet, another ECC DDR4 16GB x 2, as DRAM price crashed since last year, and recent covid pandemic affecting the market, local distributor is dumping the stock, make it more affordable now. 

I guess this is the right time to beef up my desktop Ryzen with ECC memory.

How much did you pay for these ?

About 80% of those bling-bling RGB ... yuck ...  GSkill 3200MHz rated RAM.

Does freebies count? I was given an almost new looking Cole Parmer two-stage vacuum pump yesterday, and today I slapped together a little table as high vacuum station for it, and my turbo.

10^-9 mbar ultimate vacuum when it's finished!

Oh, and I bough an "active inverted magnetron" vacuum gauge on ebay for 10 usd..

I'd say the vacuum gods must be pleased with me.

What software do you use with it? For HF I usually use Linrad

A number of other programs work to various degrees. I use it on my receivers 24 bit sound card. with a big extra ground grouding the two otogether better. That reduced noise from the cables a lot.

 

A SoftRock Ensemble III Rx Kit, a few toroids to wind and some SMD, nothing too nasty. I am interested to compare it to my HPSDR (Atlas, Mercury, etc).

It was a fun kit to build, I have the transceiver kit started but have been too busy to get back to it. (all boxed up and the printed manual in the book case). It works okay, the receiver does about a microvolt for 6DB SNNR, It is certainly usable. It wasn't a hard kit to build although, if your eyesight is worse than my eyesight (20/300) you might want to get someone to build it for you. A lot different than that Heath SB-301 I built back in 72.

Oh, you bought that one. Envious. LKB Bromma was a Swedish company known for its very high quality lab gear. Please check for RIFAs in it, because RIFA (now part of Kemet and with no manufacture here) was also a Swedish company..

I don't think that i saw RIFAs when i opened mine, but i didn't really search the PCBs for them either. One thing you should do is to check the 2W 5.6 Ohm power resistors that are between the two secondary transformers and the positive/negative output, those tend to get cooked when someone connects a low resistance load (the 2W resistors are in series with the output). Happened to one of mine, a (ebay) buyer thought that electrophoresis and electrolysis meant the same thing and complained why his electrolysis cell wasn't working... Go figure.

I got a second eprom programmer today, a TL866II Plus - it’s a great little unit, I’m very impressed.

Nice. I see you've got great taste in soldering stations.  Do you work with optical fiber stuff?

I have a similar setup and I have troubles with these transparent boxes. They tend to fall off. The pegboard is connected to a desk with adjustable height. Whenever I change height the pegboard shakes and boxes fall down .
