Pizza looks good Al (so did the punjabi beans). What did you do for the crust? Any particular recipe? I know this was back in May...

^Is that the guy who is selling some on diya as well? I think it is, and I would bet that those are genuine.

2SK170 and 2SJ74 are the singles for those. And there are the Linear Systems versions (LSK389 and LSJ109 or variants). Of course the majority of the original Toshiba parts on ebay, aliexpress and even some suppliers (dalbani and their ilk) are fakes.

RIP Mr. Lewis. A true icon and a big loss!

Yep! RIP Grant.

^ The large cap version allows a shorter height board for use in a 1U chassis. The version which thuytn mentions (.47) also uses the to220 schottky rectifiers, and has dual outputs. This is the version I would use unless I needed the shorter height.

Quarantine watching: Finally finished watching Ozark season 3. Ending kinda surprised me a bit. Penny Dreadful: City of Angels (Showtime). Show about race riots in LA pre-WWII, with some Hispanic religious supernatural stuff, as well as Nazi party activities in LA, thrown in. This one was pretty good I thought. Not sure if there will be a season 2, but I hope so. I had watched the original Penny Dreadful (also Showtime) previously, which is set in Victorian London. Perry Mason (HBO). A remake of the classic show from the '50s-'60s, this time Perry is a private investigator, set in 1932 LA. Only up to the 4th episode, but pretty good so far.

Happy Birthday Jose!

Happy Birthday!

Happy Birthday Mike!

Happy Birthday!

$135 for an IEC power cord is a lot of snake oil. I've built a few Bob Crump Asylum power cables, and honestly can't tell any difference between them and generic hd 14ga IEC cables. For a CD player, very little current so even 16ga would be just fine.

I'll take a stab at your questions. I haven't built the full size SMT Dynalo, but have built a few of the mini Dynalo's, which are pretty much all SMT. The resistors for the mini are all 0805 with the exception of the 20R, which were 1206. Vishay TNPW 0.1% 25ppm were used for most. I'm not sure on sizes for this version however. Kevin's schematics typically do not show power rail bypassing on them. Follow the board values. These appear to be LEDs and not caps. Kevin normally specs 1.7V red LEDs, such as Liteon LTL-307ELC. I don't have a BOM for the full-size SMT version. This project is still a very valid amp. Some would suggest the current feedback amp (CFA-2 or CFA-3), and I might concur with that opinion. Be sure to use the golden reference power supply (GRLV) as well, as it is very good and makes a difference.

Lots of peeps have had problems with Dalbani selling fake shit. I'm not so sure I would be so quick to think the Mouser IXYS parts are your problem... possible, but not likely.

Happy Birthday Kerry!

Shit... I didn't realize that he had passed away, and just recently too. RIP Albert.

What Von Schweikerts do you have? I've owned a pair of VR4 Gen IIs for a number of years now; still happy with them.

The case looks decent... something from ebay/aliexpress? It looks like the switch was drilled for a Bulgin type vandal switch...

I always thought L100s sounded like shit back then. Decent (re: punchy) for rock, but not much else. I much preferred the Infinity Monitors we had (and the ESS AMT-1s). EDIT: BTW, Nelson Pass is a fan. https://www.diyaudio.com/forums/pass-labs/354985-ess-amt-unpack.html#post6217253

Yep. Never bought from them, but littlediode is a known fake seller, though IIRC not everything they sell is.

^ Yes it is. When I first looked at the pics, I thought the pot shaft extender was a pencil...

From the schematic I have, the 500K resistors are from the inputs to ground, so would be in parallel with the volume pot. See if that value changes as you move the pot from 0 volume to full. That said, measuring resistors in circuit will give you sometimes strange results as you don't know the exact interactions with connected components. Also, ohming out resistors for what is suspected to be a leakage problem won't really tell you anything. Can you post detailed pics of the amp boards? Are the resistors lifted off of the board, or installed right on the surface? And what is the origin of this KGSSHV? i.e. who built it?

Some of us do or have used PRP PR9372 resistors in the past. Things I've noticed about them that I don't like include the epoxy or other jacketing used on the resistors is fragile and easily damaged. The 1/4W variants are rated to 300V; 1/2W and above for 500V. I would presume that actual performance meeting this rating would depend on the integrity of the jacketing?

Is VT4C still around? Their website has been down for quite some time. Is the pot itself grounded to the chassis (thru the nose)? Other than that, what Doug said makes good sense.

Anyone used a Grace F9e? Almost snagged one today... seems quite interesting.
