Yeah, I have wanted to get an eico for awhile but with the prices I figured this would be a good alternative and it does seem in pretty good shape, I see a little rust so maybe someone knows a good remedy for that. It is a bummer that it's for ceramic but I'm going to build a mm tube phono soon so it should be better and more quiet on a separate chassis.
This one runs 6aq5 so I thought that was cool plus they are cheaper than 6bq5. Picked up a matched quad of RCA black plates to go along with it. It will get looked over, recapped, resistors checked, replaced diode with uf4007, I need to look into the tone o matic, I guess it may have a couplet.
I'm obsessive with my temp gun whenever I first restore or build an amp so I'll make sure it doesn't get crazy hot, if so I'll have a small fan blowing.
You should also be on the look out for the 6094 tube by bendix. It is built for aeronautical use and is ridiculously over engineered. You can sometimes run across them for pretty cheap.
I will be looking for those, this thing also runs some 6eu7s which I have plenty of so won't be rewiring those. Sounds like you have a pile of amps collecting dust primo, somehow I already have about 10 amps and a few radios from just the last 6 years or so. If I keep this up I'll have about 100 by the time I retire.
Looks like the 6094 is a el84 sub? Not 6aq5?
No, it is a 6aq5 sub. You can also use the industrial type 6005 which is way cheaper than the Bendix.
Let us just say there was a period where i put my 'inheritance' into tubes and tube amps. Luckily, it was about 30 years ago, when you could get them for pretty good price.
Sorry, about the bum steer with the 6094, it is not a direct sub as FC pointed out. At least i got the 6005 correct. I hope you did not buy a thousand dollars worth of Bendix 6094 in the meanwhile!
I looked around and figured primo meant the 6005, nice post about the tune o matic, yes that is what I meant is there a difference? I very well might being doing that well I'm at it. Hopefully I can get the schematic because it's not original, someone has changed a few filter caps so who knows what else could have been touched. I'm ready to hear this thing and compare it to some other tube gear. Btw happy 4th to everyone!
It's all good, I figured out what you meant. Lol well if I did drop some money on the 6094 at least I could use them in one of my other amps lol they are pricey though.
The 6AQ5s are output tubes. The amp is push-pull, so there are four 6AQ5s, two for each channel. There are also three 6EU7s which serve as input and phase inverter tubes.
