To Do List & Procedures
Calibration Tests To Do:
Digitize Frequency Test Tape on all decks. Compare levels from each deck.
Check that both D13 & D14 mkIII models are digitizing at the same levels. Note for example that WP-31 and WP-32 are from a set, presumably recorded on the same gear, yet WP-32 is lower in levels. WP-31 was digitized on D13; WP-32 on D14.
Tape WP-32 and WP-33 were from the same set. Retransferring WP33, and future sets, so they are digitized on the same deck as other set member tapes.
Compare levels and sound samples before and after head demagnetization process.
Diagnose more about the tick sounds on Deck 12. Digitize with no tape. Digitize with blank tape. Try Metal tape. See if it's possible to reproduce same ticks on any other decks. Open chassis and try the wooden stick test. Look for blown caps. Measure voltage from psu.
find maintenance list -- check pinch wheels. figure out if there is a way to test for flutter (as a diagnostic for other issues) - perhaps record a clean waveform on tape and then look at digitized version of same soundwave
Before demagnetizing, digitize calibration tape for first 20 seconds on each deck. Do again after and check difference.
To Buy List:
new battery for APC UPS
Quick-cleaning cassettes for volunteers
rubber rejuvenator for pinch wheels
replacement pinch wheels for those needed
Mac Updrade Items: SSD, RAM, CPU
External Backup Drive
Small Server with Gigabit and USB 3.0 for saving across network to shuttle usb hdd & bkps
Go back previous to WP-31 and find any sets. Redigitize the 2nd tape in each set so it's captured on the same deck as the first tape in the same set.
To Bring:
P-Touch Label Gun - label iMac Property Tag
