I'm trying to get a little more headroom from my YBA200-2 head and I was wondering which of these tubes y'all would go for in the V1 section(stock setup is V1-12AX7, V2-12AX7, V3/Splitter 12AU7, the 12AX7s are Sovteks and the splitter is an EH). The 12AT7WC caught my eye first but I was wondering if it would make a difference compared to the older model (12AT7EH). The 12AT7WC has short plates to help reduce microphonics and noise. The 12AT7EH is said to have a deep low end response thanks to the long plate making it an excellent choice in reverb driver and phase inverter stages. However, use in high gain preamp stages is not recommended due to potential microphonics. Would reduced microphonics be something I want? I like the EH tubes and I plan on replacing all the stock tubes entirely with EH tubes by the middle of summer.
