Beolab Penta 6603 MK1 restoration project
in Imported Content (Unmapped) · Jul 10, 2016 16:05 GMT

Well after a year and a half I finally was able to recover my amplifier from the shop I'd left it with. What an absolute nightmare. After paying them for the botched repair and bringing it back they said they would get i…

Sorry for several months passing before an update, but I was waiting on someone else. I ended up dropping the amplifier off at a well regarded shop locally to have it looked at. The company I work for sends him assorted …

I haven't had any luck finding a superseded part of the transistors via google. Just a pile of links to Chinese junk knockoffs. While Google and the internet in general is a great resource sometimes seeking sage advice f…

No, I'm sure I've said as much earlier in this thread. I have an interest, learn quickly and have steady/capable hands. I knew I could handle the recapping of the crossovers and that is what I originally set out to do. T…

OK so please correct me if I'm wrong but TR25-27 (SC3281) and TR30-32 (SA1302) are the output transistors? Initial investigation looks like both of those transistors are NLA from Toshiba and difficult to source unless yo…

I'm not too worried about the small amount of money put into the amplifier components. 90% of the monetary investment was in the crossovers, and ultimately if I can't get the amplifier working I will run the towers bypas…

Well sorry for the lack of updates, not that I think anyone is on the edge of thier chair to hear about whats come of this project... but some things came up in life and I had to box the parts up for a few weeks. This ev…

While I'm certainly not going to argue with any of the points you've made the fact remains that the components are bought, paid for, and installed. No sense doing anything else at this point. I was aware of that fact tha…

I finished up both boards, PCB 14 and PCB 15. I got them reinstalled into the housings, I did have to trim the inner stiffening ribs just a touch on one side to make enough room for the 2 68uF caps to nestle down in ther…

No, not at all. Many snags, tears etc. I'm not concerning myself much with cosmetics as of yet. Focusing first on getting them functioning as they should.

It's no interruption, this is a discussion forum after all. We are all here to discuss things :-) I hope to be able to finish the crossovers tonight and be able to do an A / B audition with the two towers run by an exter…

Hey no problem! The P/N's are all there for you, but I would double check to make sure the MK2/3 crossover components are all the same. I only have MK1/2 service manual PDF's. It is sort of unfortunate that Audyn doesn't…

Sure, here is a screenshot of the shopping cart of the order I put in through Parts Express. The Audyn MKP caps are a bit expensive, and they are HUGE because they are all 400v. Lower voltage would have been a bit smalle…

Yes actually I tried to reinstall that one board last night and noted that the large 68uF cap isn't going to work right there... I'm going to have to run longer leads and locate it off board. Same with the 2x 68uF caps o…

PCB 15 as was original.... PCB 15 with the new resistors and MKP capacitors. Can you say OVERSTUFFED?

The order of all the crossover components came in today. Its going to be fun to fit all these huge MKP caps into the space where the electrolytics were. Some of theses like the 68uF ones are HUGE!

Pretty disappointed. Package showed up from Mouser a day late with the red Wima's, and the 10uf C25 caps are huge. Don't know how I missed them being 30mm lead spacing instead of 5mm like the others... oh wait its becaus…

Well checking them would be nice... but I haven't the slightest idea what to check for. If anyone cares to teach and its something I can check with a DMM then I'm all for it. Otherwise I'm a risk taker heh... During init…

Well its a little late to look at each component and replace them one at a time. I desoldered everything in one pass and then went back in to solder the new stuff in. I guess I will just have to cross my fingers and see …

Most of my parts came in today from Mouser, all I'm waiting on now are the red Wima's. I desoldered everything on board 1 that needed to come off, all the big resistors R99-R104, both trimmer pots, IC2 and all the electr…
