Steve from Canada has just sent us some pictures of his latest creation. This one is fantastic!<\/p>\n

Here’s what Steve had to say about it….<\/p>\n

Hello everyone, meet Flash-Quattro.\u00c2\u00a0 That means “four flashes”.\u00c2\u00a0 I
\nchose the name because the 807 tube is very art deco and it made me
\nthink of the 1930’s series ‘Flash Gordon’,\u00c2\u00a0\u00c2\u00a0 and there are four of them
\nhence the name,- simple!<\/p>\n

This is the latest version of the ‘Book-shelf’ amp series, like the
\nCaterpillar and Firecracker amps, this one is long and lean.<\/p>\n

Now about the amp, it’s a push-pull 807 putting out 40 watts per channel or so,\u00c2\u00a0 in tetrode.\u00c2\u00a0 Rectification is with a 5R4, but you can choose to use 5U4
\nor 5Y3.\u00c2\u00a0 All supply the amp with more or less voltage and will change
\nthe personality of the sound a bit.\u00c2\u00a0 I like the 5R4 so that’s why it’s
\nthere.\u00c2\u00a0 Input tubes are a trio set of 6SN7GTB’s.<\/p>\n

The output transformers are those nice Seeburg units that have Ultra-linear taps, but as I mentioned, I connected them in tetrode because I prefer the
\nsound of tetrode.\u00c2\u00a0 These outputs have impedance taps for 1,4,8,16 ohms.\u00c2\u00a0 A selector switch on the back of the amp allows you to switch
\nimpedances ‘on-the-fly’ so you can choose and compare the taps you like
\nfor what ever speakers you’re using at that time.\u00c2\u00a0 There is no problem
\nusing the 4 ohm tap on an 8 ohm speaker, it how it sounds to you.<\/p>\n

The power transformer is a Lowrey unit and a plate voltage of 373 vdc.
\nClassic green jewel light and side toggle On\/Off switch.\u00c2\u00a0 Painted by my
\ngood friend Joel Luttrell, and having his signature touch, a flawless
\nmirage of firecracker red (yes the same red as used in the
\n‘Fire-Cracker’ amp) and ice-pearl sparkles.\u00c2\u00a0 Apparently a fly decided
\nto do the back-stoke in the final coat of clear, so Joel had to pluck
\nout the fly, buff, and add more coats of clear.\u00c2\u00a0 Knowing Joel, there’s
\nprobably 10 or more coats of clear here!
\nTake a look…..<\/p><\/blockquote>\n
