I put a o scope on the output of my mth gn S2 4-8-4 and the waveform distorts quite quicky and the volume is not all that loud when it happens. If you are running the sound at wide open you are really getting a bad distortion of sound. At low volume a pure tone like a bell is quite good on the scope. Lionel legacy sound can go much louder before distorting. I tried using a 8 ohm speaker on mth and the waveform stayed better and on a 16 ohm speaker it did the best, but not real loud. If you are not a volume freak try a much lower volume or change to a 8 ohm speaker. 8 ohms and reduced volume was quite good. when the bell is ringing, engine chuffing and whistle blowing it is a mess. The whistle takes allot of amplifier power. Mth needs more clean power or trying different speakers. I now run my bell at volume 2, whistle at volume 3 and chuff at volume 4 and crew talk at volume 6. Use a 8 ohm speaker and all is much better,
