Hi, I have several CV5843 Twin triodes, do they have a civilian equivalent and are they any use for audio? Google shows many of the part finders offering to sell me them but little else. Steve H

I am working on the next part of NFB101. It is turning into a a huge mass of maths which I think will put off a lot of people. So I decided to split it into two parts. The first covers the basics and then when the maths gets heavy it just quotes the result and refers instead to an appendix where the heavy maths resides. That way the main section can concentrate...

I did report recently here on the qualities I found in Jolida 502 OPTs. There must be many ppl with these amps and a Google search will now bring up my experience with the Jolida 502 and its repairing. One of the pair in an amp got some shorted turns and both have now been replaced with Hammond 1650P OPTs, which are 6k6 : 4, 8, 16 ohms. The original...

Its been said here many times that plate curves for a particular tube look good. So what do good curves look like? How do you tell them from not so good curves? Adam

I've got an 11 year old who is interested in playing the bass guitar. I bought him a used Peavy KB 60 keyboard amp to get started and to see if it was what he wanted to do. It is. Problem is, the amp is too heavy to drag to a buddy's house for jamming, so I looked around my shelf and found a Heathkit EA-3 mono tube amplifier that I can mate with a 10...

Recently I got the job of fixing a Jolida 520 stereo integrated power amp with 2 x 6550 per channel in UL class AB1. After 12 years of use, one channel had developed a shorted turn in its OPT, and the owner agreed with me that because the support provided by Jolida and the shop who sold the amps in the first instance was so poor that it'd be wiser to...

I have a nice Marantz Model One mono preamp (no power supply) in original wood case. It has the original Telefunken 12AX7s, and is completely unmolested. Condition is very nice. I have not tested it, since I don't have the power supply or cables to connect it to my MC-60. It came from an estate sale, and was stored in a bedroom closet for probably 30...
