  6. FWIW, I just added a couple before and after XO pics to my post on pg 2
  7. Is there a label on the back of the speaker? It should list the finish. have a look look here:
  8. I don't have a Crown amp but installed a Noctua fan under the tube cage of my Bob Latino VTA ST120. They make a zillion fans of different sizes and specs. They were also helpful with questions. https://noctua.at Hope this helps someone.

    Miracle whip

    Though my usual is Hellmans, Kewpie is pretty good if you're near a Japanese food market. We first had it at a sushi place. A lot of them around here use it. https://www.kewpie.com/en/products/mayonnaise/
  10. "So all that aside, one of the speakers is not sounding the same as the other. A visual inspection of the drivers and horn do not show anything obvious. I am thinking the crossover may need to be disassembled and recapped. I am not finding any indications anyone has done this before and that there is very little information on this task." I recapped my RB-5 Mahogany(s) about two years ago. I got the parts from Crites and a schematic was included. They don't list this speaker on the site but I asked and sent them the ser #'s and xover pics. I didn't mess with the diaphragms. I have more pics of the before /after, etc but not tonight- LMK I honestly couldn't say if I noticed an improvement but I figured they were old enough so it couldn't hurt. Also they're not in an ideal location so this may be part of the sound issue. Sorry about your grills. As for your sound- check and tighten all the internal spade connectors.
  11. No R2R experience whatsoever. Just putting this out there: https://store.acousticsounds.com/index.cfm?get=results&saleid=515&banner_id=317
  12. Just saw this: https://www.ebay.com/itm/224424049020?hash=item3440b7397c:g:7g4AAOSwmBhaB4UW I have no experience w/ the tool, only a positive one with the seller.

    Carbon Steel Pan

    Mine is the 10 1/4" Matfer Bourgeat and the video mentions it's interesting seasoning instructions. The OP knows his way around cast iron so seasoning shouldn't be an issue. I followed the manufacturers instructions. I use mine for all the non baking things you'd do with cast iron. It weighs about 2/3 as much as cast iron. I like mine. I got this: https://www.amazon.com/gp/product/B000KEJQJ2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 based on this:
  14. No experience w/ the brand however I saw this thread from 2014 on another forum I frequent. Don't know anything more and things may have possibly changed... I hope. https://dynacotubeaudio.forumotion.com/t2097-sophia-electric-virginia-usa-yeah-sure?highlight=sophia
  15. My VTA ST120 kit- Pictured w/ TS 6550's and 5AR4. Now running KT120's, S/S rectifier w/ Autobias, Clear top RCA 12AU7's on the outsides w/ Brimar ECC 82 in the middle.
  16. What did Bob and Roy have to say about this? There must be some kind of support as it was built for you. Have you searched on their forum: https://dynacotubeaudio.forumotion.com I built mine from a kit. Bob was super helpful and very responsive. I never had an issue with my TungSol 5AR4. I never installed the 5AR4 that came with the kit. I'm keeping it for a spare. After about a year and a half, I had the auto bias board installed. I then switched over to a Weber WS-1t s/s because of the built in delay. All's fine here. Hope you get it sorted out as it's a great sounding amp.
  17. http://www.tubes4hifi.com/ST70.htm has a TDR board that may be helpful. You might have a look here: https://dynacotubeaudio.forumotion.com From what I understand the S/S rectifier uses 17 volts less because it doesn't need heater current. I use a Weber WS-1t in my Bob Latino VTA ST-120. Prior to this I was using a Re-issue TungSol 5AR4 with no problems (about 1 1/2 yrs) I got an auto bias board and this also has a delay so I got the S/S. I don't hear a difference. Both Kevin and Bob L are good guys to deal with in my experiences.
  18. Any luck? My ST-120 has the auto-bias board and a Weber WS-1t (optional thermistor). It's working fine but I had a tough time with the AB install. All fine now. The KT-120's bias 0.49, RCA 5963's on the outsides and a Brimar CV4003 in the middle. I'm also on a variac at 117v. Pavel was very helpful as was Holger at Erhard Audio. Prior to the AB and Weber, I used a TungSol 5AR4 and never had a problem. Amp and variac once blew a fuse but I don't recall why. Have you done the "yellow sheet mod"? It's on the Dynaco forum.
  19. You might try Holger at https://www.erhard-audio.com He's the man in the US and he helped me out a lot with this. Pavel in the Czech Republic designed and makes the board. He is helpful but English isn't his first language. There's also a time delay depending on where you are but, he is responsive. https://www.audioamp.eu/en-detail-901899168-modules-for-to-optimize-bias-with-an-supply-of-bias-ab-q-st70-st120.html Hope you get it sorted out. The ST120 is a fine sounding amp.

  21. Here's the manual that came with the board. http://www.***.cz/files/AB-Q_ST-70_ST120_manual.pdf Once it's set to the desired bias voltage by the installer, there's no real hands on. Make sure they know what tubes you're using and clear it (voltage) with Bob. I was still checking my bias for a bit after installing but all 4 tubes were always the same (as designed). Hope this helps. Bob was/ is a pleasure to deal with as well.
  22. I agree about the install- do it all at once.
  23. Bob is right about the AB. I got it and had issues getting it installed. Everything was great prior to adding this. I got the PIO caps and the attenuator these are positives. I’m using KT120s, a center Brimar CV4003 and Bob's NOS RCA 5963’s on the outside. Amp sounds great and bias was always very close when I checked it monthly. It’s now spot on w/ the AB but that complicated it. The AB does have a delay so I got a Weber WS-1t s/s rectifier. All in all, it’s a great sounding amp.
  24. I have a Latino VTA ST120. It sounds great and sound characteristics can be tweaked a bit by tube rolling. I don't have Khorns BTW. You could search or pose the question on that forum: http://dynacotubeaudio.forumotion.com
