I had to take out the (many!) screws on my Ultra SL preamp (12-inch case) to replace a bad tube this past weekend and only put about 4 back in until I was sure the new tubes were OK. Of course the Mrs. inadvertently threw out the ones I didn't put back in.
Anyone know the specs on these so I can go down to the local ACE and get some more or where to get some? I'm sure Frank has them but if they're readily available I can just get them myself. - Thanks.
