A minor project but still challenging for a freight guy like me.
I picked up this SB-200 for $150 and installed the soft- key module on Sunday to complete the last of the Harbach mods. The amp has the soft-start, new power supply module and soft-key, It also has two strong Cetron 572B tubes making about 750 watts with 65 watts drive. I was considering picking up a pair of the Chinese tubes currently available on eBay, while they still are available, and storing the Cetrons for backup.
I really like this amp even better than the AL-811H I have but 811 tubes are in good supply and still pretty cheap for a matched set of four.
