RIP, Bob. He helped me with noob questions and always patient. A true loss.

Please ignore this post! I solved the problem.

Here is an old thread about this very issue.
Super - Thanks!!!

Thanks Robert for this info - I have read about the Tung-Sol and are on my list to try - but I had been reading about their power tubes. If I can get those little tubes out of their aluminum cylinders, I can find out what I currently have.
Now that I found out I have the B, I also discovered that I actually own all the original service and operating manuals for the B in my drawer along with some notes from the tech I bought the unit from (He had been a tech for HP). These have some information on how to set the bias - and even mention an adjustment for hi fi collectors to push their units a little less.
Cheers!

What substitution did you google? 7189 is the correct output tube for a Scott 299B. You might want to read about Russian surplus 6P14P-EV . (6П14П-ЕВ) EL84 might be OK. Google these tubes - you'll find lots to read.
7591 is NOT the correct tube for a 299B. (7591 is a completely different tube. It is used in the 299C.)
Here's a good reference site: http://hhscott.com/integrated_amps_stereo.htm
Thanks again, Robert! - again, you are right - I had been googling 7591 and EL84 all along and that's why I hadn't found any useful results.
I just googled the correct pair and they are indeed possibly interchangeable, the big difference being the operating voltage of the circuit. The Scott 299-B appears (anecdotally?) to operate at 355 volts which is higher than the EL84 rating, but not quite at the 400V rating of the 7189. That was probably a measured voltage and not necessarily nominal. Now, given that the amp has performed fine for the last 8 years, perhaps because I have never had a need to push it too much with the La Scala's efficiency, is it safe to assume this configuration is safe electronically? Then the final question remains of would the sound characteristic of the power tubes be much different between these two tubes types?
-
Those tubes are totally different. I don't recall seeing the “C” version with EL84s in the output stage. Are you sure you don’t have an earlier model?

Oh - you are right! It’s a 299-B and I never knew. That being said the power tubes in the B should be 7189.
It sounds good to me and other than one blinking light it performs flawlessly.
I did google search for this type of substitution and found nothing.

Hi all,
I have a Scott 299-c for a number of years now, and have it happily paired with La Scala's.
I recently considered rolling tubes - I noticed its 4 power tubes which normally call for 7591's
actually have Ei Yugoslavia EL84's.
Does anyone have experience with using the EL84's in this config, and what are the pluses and minuses
for not using the called-for 7591's ?

Hmmm.... somebody more OCD than Dean... nice!!
OCD are my middle initials!

It certainly makes all the difference, in my experience.
Dean’s x-overs are works of art!

Yes - they are positioned with the length perpendicular to the front. I will post a photo of why i can't wedge it in the other way to be able to see the metal signage to face the back after getting past the 2MB photo trim...
I see given y'all responses, that I probably need to just lighten up, and enjoy! I think part of the frustration is I see the backs of my La Scalas every day, as they are placed in the middle of the room (due to the logistics of my space. )
Cheers!

Hi dean,
yes that is how I currently have it. It just bothers me enough to want to rejigger it!

Hi all,
I have those orig klipsch AA crossover whose longer form factor (from Klipschorn?) that doesn't fit my La Scala
(the long side of the board can't face outward due to it being too long).
Has anyone McGuyvered a way to reconfigure the least number of components and shorten the board to fit the La Scala?
I've already replaced the oil cans with audyn caps so that real estate has been opened up...

Hi all - I've got 8 DBX encoded records in Jazz and Classical. They can only be played with a DBX encoder!
I'd prefer offer as a single lot, and I will double check vinyl condition with visual grade before finalizing - just PM
me if you have any interest - at least the album jackets are in the EX+, near mint range and many or most came with the special
DBX inner sleeve and all the inserts - at least I haven't bothered to touch any.
$102 includes shipping to the US only - ($99 if paying by friends and family or some non-fee method).
If you prefer to buy any individually let me know and I'll work it - thanks.
PS I have some non-DBX audiophile records that are MFSL half speed master recordings if you wish to learn about, just PM me.
(Big rock list still to come too)
-
I'll post the prog by message to those who asked and after you get a personal chance to buy, I will append them to the public list. Thanks
-
No beach boys. Prog rock is limited to bands like Alan Parsons, Supertramp, Pink Floyd, one Crimson LP. I will work on some classical and opera next. All the best.

I will have classic rock, a little folk and a bunch of classical. I don't think there's any blues - but I will be on the lookout. The majority of these are almost new as if they were played once for taping purposes, but not all. Thanks for looking!
-
I have some LP's that I'd like to sell. They were very well taken care of.
Many appear almost new, while the rest may have minor sleeve wear.
In any event if you indicate interest I will PM with any details of condition
after inspecting more carefully (esp vinyl condition)
DOMESTIC SALES ONLY! International shipping is nuts these days!
[update: for records sold, indicated below]
I have other genres too - just thought I'd try one first.

That looks normal to me.
I never looked that close.
Looks like they're wrapped in Teflon tape, and then another layer with the label. I wouldn't sweat it -- go for it.
Thanks, DeanG
All the best!
-
Thanks for the help - here's a pic of the back seam - label is slightly misaligned on the right edge. the finish of the label is more like an eggshell finish rather than glossy like my other brand caps and the 0.15uF I saw online. I can't really tell if it's the Teflon tape or an additional wrapper.
I'm just getting around to replacing the oil cans that leaked their contents during USPS transit!
Thanks! (I need a manicure too)

Hi,
I had a question about the Audyn Cap Plus 2.2uF. Should this product have what looks like an embossed "sticker" wrapped around the capacitor? I've seen photo of the .15uF version where the product info/and branding appears to be embossed directly into the plastic casing itself, leading me to wonder if the 2.2uF is legit.
Thanks!

Sadly, I was recently mailed a pair of vintage AA crossovers, a couple of whose oil cans (thankfully the 2 uF's and not the 13) tore off in transit and leaked their guts out into the cardboard. The packaging left much to be desired, so the situation seemed avoidable - not the best size priority box and packaging used for those stand up oil cans...
Would a "sticky" on how to properly mail a pair of AA's (by priority mail using a standard size box?) and the current costs be in order? The same goes for any of these speaker parts really...

"Value" and "improvement" (or "better") are pretty subjective terms.... "trounce" is a pretty strong one!
They are all compromises of some sort and what the OP wanted to hear about was the pros and cons.
I skipped the pros and cons and went straight to what I would do which is to try both.
Thanks - I really appreciate all the ideas - altho making a decision to do just one is harder than ever!
To be sure, when weighing the two, I was assuming a comparison of approximately equal value. That is, an Super AA/Alk Jr is about $99 for Al to do, while a (sonicap) recap kit is $96. I didn't want to spend a whole lot more. These 55 year old ears I figure aren't investing much more...yet - I'm all ears!
Perhaps my post should have been...I got an old pair of AA's and $100 in my pocket. How do I best spend it? (Or am I really short changing myself, which seems consensus).
-
Thanks - I have both the original square magnet and Crite's CT-125 to choose from at home, so if I go the way of the Super/Jr and find the original too hot, the CT-125 might sound tamer. If I do stick with a straight AA, I don't anticipate doing anything bigger than a recap - at least for starters! While I was comparing the Super exchange against the Crites recap package, reading thru more of the forum I see the Russian PIO, Dayton 1%, and Jantzens. These seem to be among the modest budget directions that people are going when replacing the oil cans.

Hi,
Wondering if anyone out there has partaken in AlkEng's Super AA exchange program, and weighed the sonic pros and cons vs doing a straight AA recap.
Thanks
