I spoke with Phil at Heyboer this morning. Phil is a very nice guy and gave us the price break we wanted. I told him we had four orders, and he gave the price as though we had five. The final specs are: - 100 mA capacity from the HV (400-325-250-0-250-325-400 mulit-tap) - 3A each of 5V and 6.3V, one 5V and one 6.3V - both of the heater windigs CT The cost is $66.30. The bill will be sent with the order and is payable in 30 days. The ship time is two weeks. When you call Phil (616)842-5830) to place your order, reference HTS-8074 or my name, Colin Hester. I did not ask how this will be potted, so if anyone has a preference I'll go along with what ever. Let's make it easy on Phil and all be on the same page. I did place my order today. Please sound off when you've ordered......Colin

Hey-Hey!!!, Colin, you ref'd potting. I think you guys are getting an unpotted version, $66 is too close to the premium paid for potting. Vertical endbells, like ST.70 outputs, or either of the Dynaco Mk.III's irons. Spent the evening wrestling with layout on a 18w x 13.5 deep top plate. The box is 5" thick and in some places I am running short of room. Three L-C filters, two for the filaments, and the main HV give this thing a mass like a respectable power amp. I am losing a half inch at each edge, so the realestate is a bit smaller. If you guys go for the top plate and wood base construction, getting a haldle on it to pick it up is sometimes a PIA. Take a 1" holesaw and at the lower edge make four overlapping holes so you can stick your fingers in. Make the edges a bit rounded, and it is a great sol'n to the trouble of sticking handles somewhere. regards, Douglas

12x12 ought to be plenty. Remember, I have twice as many things, and most of them are bigger. The amplifier section is made up of 6 valves, 2x 12B4A and 4x 12BY7A for the active loads. The first one of these I built on 5 3/4 x 11. I am going to resurrect it with 12B4's and the rest of the Guinevere circuit. I was goig to use 6 1/4" but the milling machine vise only could take a 6", so I trimmed it so I could clamp in in the vise. regards, Douglas
