I just got a SB-201 , and It was hacked badly , I take some pictures and post later .
I go to coffee shops for WiFi so some delay .
I did get the builders manual with the amp , I noticed some questionable solder points , a newer style cap soldered on the bottom side of the transformer board , then on the back of chassis , a aluminum box about 1'' x 1" x 3" riveted to chassis , one wire coming out of either side , the only mention of it in the manual was where to solder the 2 wires , but no mention of what it was ?
The 2 wires were cut and a short piece of small speaker wire looped around the box to connect the circuit the box made .
The stock fan was gone , the case had a hole cut , and fan mounted on top .
Also no tubes [ 572Bs ] , I will be looking for those , it sounds like the chinezz tubes are not the way to go .
This is my 1st tube piece of equipment .
