Really good coupling caps  do influence the outcome. After I did mine on my former V12R and now current Mono Tube amps, I could THEN truly hear the differences with input/output tube changes -and- interconnect changes too. 
Best replacements for KT99A tubes?
@_rossbowerdecooney, Awesome, thank you! I have seen some people recommend the KT-90 or even KT-120 for this amp. I’d feel more comfortable using something written down in the owners manual, but I don’t know enough to really compare these options.... 
Best replacements for KT99A tubes?
@_rossbower_@decooney This is for a pair of SLM-100’s. You remind me I need to track down an original owners manual... I’m definitely planning to get matched quads. Any thoughts on EL34 vs. KT88? I had the sense that KT88’s were higher quality som... 
Best replacements for KT99A tubes?
@_rossbowerIs this for the SLM-100 or SLAM-100 monos by chance? If so, shows in the OM they originally came with 6550s. Original OM mentions max bias adjustment of 175ma for all four tubes per amp, with potential use of EL34, KT88, KT99s. Maybe go...

The stock Ruby EL34 (Shuguang EL34-BSTR) sounded the smoothest with the Mundorf SESG Evo (non-oil) Supreme caps in my V12R amp, and I was using vintage RCA EL84s and Siemens 12BZ7s or RCA 6922s on the front end (50w Triode) mode. With that said, m...

Considering A SS amplifier
@neonknight ..I seem to recall that long speaker wire is more preferable than long interconnect runs...XLR interconnect cables are specifically designed for long runs. The test was to validate it so you could rectify the situation, "loss".    Woul... 
Demo'ing Class A amps, Appreciation Suggestions from those who recently been there
@chorusAre the INT-25 and XA25 still in the running?Different amps, but also wondering if you already reviewed the INT-60 too... or heard one in person somewhere.

@oldhvymech"I did have Mundorf .22uf 1000v Supreme Silver gold oils. for the audio 1 cap swap, I also had .22uf 1400v Supreme aluminum caps."Not following ya. Where "did" the Mundorfs go? The ones to get are the non-oils for fuller sound and detai... 
Considering A SS amplifier
@neonknight The only other consideration I got is speaker wire. Use Wireworld Eclipse Series 8. But need an 8 meter run so thats not a cheap test as I cannot find a run of that length on the used market. 8M is quite a run IF your PSA/BHK amp is al... 
Considering A SS amplifier
@neonknight So far I have used it with the matching BHK Signature pre amp, along with one from Edge, and a passive from Placette Audio. So far I prefer tbe Halcro. Also ran a dozen tube chouces through it and the Telwfunken work best. Cables from ...

@aldoallen .. I can’t think of anything sound wise I would change but it is definitely not audio jewelry. Just a plain black box...aldoallen, Congrats. It is unique black box. Not like most other 10w amps. My colleagues ZOTL displaced a former Car... 
Considering A SS amplifier
The BHK 250 is a nice amplifier, particularly when paired with the right preamp and speakers.  Triode tube front-end with all-MOSFET circuitry.Might be worth saving, finding the root cause issues (likely in other parts of the system), rather than ... 
Considering A SS amplifier
Are you judging the sound of the BHK 250 based on the sound you get when paired with your Halcro DM8 preamplifier alone?  Have you demo'd other preamps with your BHK 250?
