Its a 20uf 3kv oil filled cap. I called Henry Radio and of course they didn't have it (I gave them a break.. it is 30 y; /archives//html/Amps/1999-10/msg00141.html (7,308 bytes)
2. [AMPS] Henry 2K-3 (score: 1): Author: measures@vcnet.com (measures); Date: Tue, 5 Oct 1999 03:38:05 -0700; ? Easily. My guess is that 4uF would do the job in a resonant-choke supply for 3-500Zs. The critical C is the capacitor across the resonant-choke. - later, Martin - Rich..., 805.386.3734, www.vcnet.; /archives//html/Amps/1999-10/msg00157.html (7,501 bytes)
