Hi all,
In a Nutshell (for reasons unknown) my (new to me) 2A3 SET Mono Amp (I'm thinking) is the cause of
a sudden decrease of volume on my Tru-Sonic Horn. At first, I thought the problem might be the Tru-Sonic Horn itself as I had earlier this afternoon taken the back off (VERY carefully) as I had planned to change out the Bass driver until I realized it was NOT going to be such an easy exchange so, I abandoned that plan. While I had the back cover half off, I did take the opportunity to De-Oxit the Horn's two L-Pads. After that, I carefully replaced and buttoned up the back cover. Several hours later, I turned on my SET Amp and right away noticed that the Volume was perhaps 25% of what I had experienced last night. So, as a test, I played the same (good recording) CD disk that I first ever played on this System last week (which sounded GREAT) however tonight, I'm experienced a great loss of volume. My first thought was, I screwed up something (wiring ?) to the Horn Speaker by removing the back cover (tight wiring). So, I disconnected the SET Amp from the Horn and connected my Mono Pilot PT-1030D (EL 84) Amp and, the Horn plays/sounds fine (and LOUD). Of course the Pilot Amp is 13 Watts or so (vs. the SET 2A3's three Watts). That being said, the other night, the 2A3 played equally as loud with ease. So, I again reconnected the SET Amp back up and tried different interconnects (direct from CD Player into Amp) as well as two different CD Players. Ugggh, still a "no go" for the SET 2A3 and volume. Guys, I'm not sure what to think as I'm very new to the SET Amp World. Is it possible one (or more) of the SET Tubes suddenly became weak to such an extent that it can cause such a noticeable difference/loss in volume ? I mean a night and day difference. I VERY much would appreciate any help/suggestions/recommendations on what I should do about this situation. I already miss my 2A3 SET.
Thank you in advance for any help you may offer.
