Krell FPB 700CX
Krell FPB 700 CX wanting to use tube preamp. Jumpers are advised with caps being engaged due to "potential" DC. Based on the pics attached, the jumper above labeled JMP1 for tube preamps? Purchased used and Krell is under restructuring. Any help appreciated. Thank You.

@ossidian5 You're welcome! You can engage the coupling capacitors by removing the jumpers. While almost any tube preamp can be safely used with a Krell power amp without the use of the input coupling capacitors mentioned above, some vintage/boutique PIO (oil in paper) caps in tube preamps tend to leak DC over time and can damage downstream components!

@ossidian5 the reason I asked what tube preamp you have is because some tube preamps are transformer coupled which would be the ultimate DC protection. |
