Whilst inside the amp to replace a failed rectifier, I note that some of the Solen HT caps show 'leakage' - is this simply the adhesive for the outer wrap leaking out?
Should I consider replacement, or is the actual cap likely to be satisfactory?
This one is 4µ (in the 12AX7 HT PSU) - will a 3µ9 or 4µ7 be OK?

Replace it. Caps can go bad before showing any signs of physical changes, but if I see any bulging/discoloration/leakage,... I would replace it.
BTW- I really like Solen and have used it in a number of my equipment so no need to change brand IMHO.

Re: MV-55 - condition of Solen PPE MKP capacitors
Agree re Solen - I have ordered new replacements but not 4µ - have 4µ7 as it's hard in UK to get the non-standard values.
Given the location in the circuit, I can't see an issue with the mild change of value - can you?

Solen ships from Canada. I have ordered from them directly (I'm in the US) and shipping was reasonable. I don't know if it's significantly more to the UK.
